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.

Nov 10 23:55:34.018593 Chriss-iMac.local discoveryd_helper[147]: Detailed RemoteControl com.apple.discoveryd_helper XPC connection 0x7ff9d0600210: start (pid=50, <unknown> not root)

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.

    I have a Feeling it could be Timemachine related ? Were you able to see wethere the Crash happens when a Timemachine backup is about to start ?

    I do not think that they are related. I use time machine with external drive and it was not present at any of the crash times. I am more inclined to attribute it to VirtualBox activity. I have changed the logging level and basically waiting for a new crash so I can inspect the logs ... let see.

    Same issue here after updating to Yosemite. No useful information before the crash in system log as can be seen below. User reports trying to open a pdf right before the last 2 crashes, probably coincidence. User works with files from network shares. Default pdf viewer is set to Adobe Reader.

     

     

    System log right before the crash:

    Hi,

     

    I had a crash.

     

    - Bluetooth is off by default

    - 10.10.1 was installed

     

    I did not have any Calendar account issues.

    I am having the same issue.

     

    I just did a clean install of Yosemite (formatted hard drive) on a 2009 Macbook Pro 5,4 and the version reads 10.10.1.

    The only apps I have installed after the clean install include Kindle, Garage Band, iPhoto, and Xcode.

    The only app that are open when this crash occurs include Calendar, Console, Mail, Messages, Safari, and Finder.

     

    The below logs are from Console -> LibraryLogs -> Crash Reporter

     

    It seems that the timestamps of these log entries match the times that my macbook has suddenly froze and then rebooted.

     

    Anyone have any ides what might be causing this?

    I am experiencing this crash on a clean install of Yosemite 10.10.1 and Time Machine is off and has never been configured on this fresh install.

     

    By the way, on my Mac I am only assuming that the crash is related to following log line since the log line is in the CrashReporter section of Console, but I don't know much about how to debug using Console.

    Some additional information: I just disabled bluetooth and turned on my firewall. Will wait to see if the crashes continue...

    I'm having these random restarts on a Mac Mini (late 2012) server with the same discovered_helper message in the crash reports. I had started with a clean install of 10.10, but these crashes started to occur after upgrading to 10.10.1 in my case. I don't see the problem on the other Macs (MacBook Pros and MacBook Airs) running the same OS.

     

    This Mac Mini is used mainly for family multimedia stuff and as a DNS caching server. There is not much interactive use. Interestingly these crashes all happened when nobody was working on the computer.

    I continue experiencing those. Tried chaining the discovery log level and monitor what is going on. Unfortunately discovered creates so much noise and I couldn't sift through those.

    But with last couple of crashes I noticed that the kernel spits bird message and I got also VM related complaint.

    Here is how it goes:

    02/12/2014 10:47:54.000 kernel[0]: bird[575] Unable to quarantine: 93

    02/12/2014 10:47:55.342 discoveryd[49]: Intermediate ClientIPC DNSServiceGetAddrInfo: flags=0x2800d000, interface=0, protocol=0x0, name=p14-content.icloud.com (nsurlsessiond(555))

    02/12/2014 10:47:56.477 discoveryd[49]: Intermediate ClientIPC DNSServiceGetAddrInfo: flags=0x2800d000, interface=0, protocol=0x0, name=att-us-san-stl-00001.nawest3.synaptic.att.com (nsurlsessiond(555))

    02/12/2014 10:47:57.000 kernel[0]: bird[575] Unable to quarantine: 93

    02/12/2014 10:48:00.000 kernel[0]: aio_queue_async_request(): too many in flight for proc: 16.

     

    I am still trying to make sense of all this and will keep tracking to find if I got any more useful information.

     

    Meanwhile has anyone found any more clarity about the cause of this problem?

    Same here with iMac 27" and Yosemite 10.10:

     

    Crashlog shows this a lot:

    Dec  3 19:30:09.599762 iMac.local discoveryd_helper[151]: Basic RemoteControl com.apple.discoveryd_helper Starting XPC Server

    Dec  3 19:30:09.600101 iMac.local discoveryd_helper[151]: Detailed RemoteControl com.apple.discoveryd_helper XPC connection 0x7fbf00f00430: start (pid=49, <unknown> not root)

     

    Somedays the system is running fine the whole day, others the system is randomly rebooting again and again... yesterday 4 times in a row...
