Q: Yosemite random Crash - discoveryd_helper[147]: Basic RemoteControl com.apple.discoveryd_helper Starting XPC Server

Hi Everyone,

 

i have a crash every now and then. Looks like it has something to do with Networking or Bonjour.

anyone got any idea what it could be ? I learned that

 

there is no more com.apple.mDNSResponder.plist in OS X 10.10. The service that controls mDNSResponder is now discoverd. The plist file you are looking for is actually:

/System/Library/LaunchDaemons/com.apple.discoveryd.plist 

You want to add --no-multicast to the ProgramArguments in that file.

  <key>ProgramArguments</key> <array> <string>/usr/libexec/discoveryd</string> <string>--udsocket</string> <string>standard</string> <string>--loglevel</string> <string>Basic</string> <string>--logclass</string> <string>Everything</string> <string>--logto</string> <string>asl</string> </array> 

Becomes

  <key>ProgramArguments</key> <array> <string>/usr/libexec/discoveryd</string> <string>--udsocket</string> <string>standard</string> <string>--loglevel</string> <string>Basic</string> <string>--logclass</string> <string>Everything</string> <string>--logto</string> <string>asl</string> <string>--no-multicast</string> </array>

 

but doing this (adding --no-multicast) disables finding and communicating with printers in my network and my timemachine backup drive can't be found.

 

..... any clues ? this is driving me mad.

    Random crashes have been around for a long time. In my case I have had two or maybe three causes, albeit no logs to offer:

    - 3rd party sound device from MOTU - Ultralite (also quite old - same as my Mac which is a late 2009 imac i7) is running when the iMac goes to sleep (not just the screen sleep). I can wake the MAC up ok, but for some reason after that it starts the crashing issue. MOTU has not updated the driver for a few years, so I suspect thats where the issue is. I have since switched my RAM sleep mode off in favour of storing the session to hdd, which seemed to have helped a bit and then switched the sleep mode off completely last year, because it did not fix it properly. This happened two versions before Yosemite and is still the case today.

    - 3rd party virus scanner Intego plays up for some reason. I had talked to Intego support who asked me to remove it and re-install it, which worked for me.

    - latest issue occurred a couple of weeks ago, after it was fine for a number of months. Unfortunately, I guess the keyring app stopped responding during an update, which cause mayhem on the mac when I did a hard reset. hours later after going through logs, running disk repairs, permission repairs, backing up , re-installing Yosemite (all bar a complete hdd wipe) I uninstalled Intego again and as by magic the problem goes away. I try to reinstall and on a full disk sweep it cashes again, so I removed it for now. My suspicion is that I have some duff memory somewhere this time that gets triggered somehow (although I hope not) and cannot be repaired anymore by OS X or the drive.

    - I read some articles about other entries in the logs that seem to occur before the system crashes, and in general my mac is not happy at the mo. suhelperd (I think this is related to gpu hardware monitor compatibility), nsurlsessiond (I believe this is an icloud issue), some garçon issue (dropbox), I get spindumps for powerstats (maybe the power supply... god knows).

    All in all, I am getting the feeling it might be the time to invest in a new iMac..

    Well, I'm happy(ish) to report that I found the cause of my crashes. The HDD was dropping out (disconnecting from and completely unseen by the system until reboot). Understandably, storage volumes do not react well to 66% of their media disappearing all of a sudden. I found this by splitting up my Fusion Drive, and installing onto the SSD. I had my user folder on the HDD, so when it dropped, the applications and parts of the OS that know how to run without the contents of the user folder kept running fine while others crashed, hung, or complained.

     

    So at least in my case, the log messages I was seeing were a red herring - just the dying gasp of applications that were crashing just like everything else was. I suspect the shop that installed my SSD made some mistakes (so much for saving time by having someone else do it).

     

    Obviously not everyone here is running a Fusion Drive, so that's not going to be the universal cause. For those still having trouble, go through systematically to eliminate variables. Just because your machine doesn't crash while running a different OS, doesn't mean the problem is with Yosemite. (Unless you're running a 100% Snow White Yosemite install with all original hardware in which case... well, it still could be a hardware failure that doesn't rear it's head under an earlier OS). "Random" crashes aren't really random, they're just caused by something we haven't found yet.

    I am reporting back after a week. My problem seemed to be with the original ram that came with my 2008 (3,1) MacPro 8 core. I removed it and problem resolved as mentioned in my earlier post.

    Thanks for this post tanjucat. After performing an extended AHT on my 2008 (3,1) MacPro everything checked out. I also found it a strange coincidence that my Mac Pro was crashing since Yosemite 10.10.  I decided to play around with my RAM. My configuration was as follows:

     

    2 x 1GB  Kingston RAM (original apple ram) in the Upper Tray Slot 1 and 2.

    2 x 2GB Ram Crucial matched pair in Upper tray slots 3 and 4

    2 x 2GB Ram Crucial matched pair in Bottom tray slots 1 and 2

     

    For a total of 10 GB or ram.  I removed my oldest Kingston Ram which originally came with my MacPro and placed all my Crucial Ram in the upper tray against apple's reccommendations .

     

    My mac no longer crashes. I plan to buy more Crucial Ram and see if I encounter the same once I fill up the bottom tray .

    Hi folks,

     

    I had the same problem like you have.

     

    I had up to five system crashes a day with the same crash reports.

     

    I solved the problem in the following way:

     

    I installed ccleaner for mac.

     

    I went to extras, then to startup and I cancelled all the hidden programs and services, wick are not really necessary. Only the startup programs, which are necessary, I didn't cancel.

     

    Since this action my system runs without any problems, it's stable and I din't have any system crashes.

     

    Notice: When I start VMware fusion, (for using windows), I have a crash within a few seconds. I'll kill that damned ******' program!

     

    I hope, you will have a success with my hints.

     

    Good luck!

    I have exactly the same, happened multiple times today in a row.

    i installed ccleaner for Mac its free. I found one unidentified startup program will post if this fixes the problem.

    What i have done so far:

    1.     Verify Disk utility First Aid "Verify Permissions"

    2.     Stopped using TimeMachine, (TimeMachine runs over the network via afp bonjour) Believe this could be the issue, since The timemachine backup was         erased, and is not communicating.

    3.     Ran the ccleaner tool per the post. Will updated if the crashes stop. I am on my 12th crash in four days. Only began in the last 4 days.

    I did the file permissions on bootup (by using the option key) and it didn't solve anything.

     

    I don't use Time Machine (I use Arq and SuperDuper instead but I doubt they did anything at startup).

     

    Do you have multiple USB drives connected ? I have 3 and wonder if that can be the cause.

    ******************************Solved with Explanation**********************************************

    Per ccleaner works.

    Why?

    XPC is making calls to downloaded folders files that are no longer current, if these are large files, the XPC app as a security measure will stop if they don't see them. So recently I downloaded several large .iso's. So by running the ccleaner tool, which deleted my:

    Internet cache

    internet history

    cookies

    download history and a few other items.

     

    The XPC app headers that are mapped in the cache are deleted so they are not making calls to Phantom data.

    I believe that people with iTunes or TimeMachine may have similar crashes because XPC works with them in a security manner, and if you have large files such as itunes, or iphoto, etc the same result can happen.

     

    *****************************Crash Free*************************************************************

    Check out this article on Developer for more info on XPC, happy computing.

    One Step I did not add, when running ccleaner go to 'tools' in the side menu, & startup (this step is mentioned with user, )

    Remove any startup service that you do not need.

    Hi,

     

    what helped me in the end was uninstalling my virus scanner - which I have not yet switched back on. By the time I figured that, I reset all the transient RAM, switched my scheduled reboot off, had multiple reboots into safe mode, disconnected and reconnected my USB devices, updated jbridge kernel extension that gave some errors during boot, and finally reloaded the OS X from the recovery disk. I have run the MAC since then 24/7 and not a single crash - about three weeks ago.

     

    Also, I have switched verbose boot on, so I can see the messages during boot and since latest OS release the hardware error messages have disappeared and it's looking quite ok now. Keeping my fingers crossed

     

    Kind regards

     

    Andreas
