open(Not Responding) in Activity Monitor

When I opened Activity Monitor, I found one line that showed PID 93 was open (Not Responding). The Info showed the Parent Process as launchd (69). Under the open Files and Ports, I got the following message:

/
/usr/bin/open
/Library/Caches/com.apple.LaunchServices-023501.csstore
/usr/lib/dyld
/private/var/db/dyld/dyld shared_cachei386
/dev/null

count=0, state=0x2

I've clicked Quit Process on it, but it quickly comes back.
What does this mean? The fact that it says Not Responding and is in red in my Activity Monitor makes me worry. Could this be slowing my computer down?

Thanks for any help 🙂

What was the name of the process? If it's an application at least you can force quit it. What you may have is a launch agent or daemon that relaunches automatically. Does it become unresponsive even after you force quit it?

In the process name column all it says is open(Not Responding). So I guess the process name is "open".
When I force quit it restarts automatically and then goes to not responding pretty soon after.

OK, you might give this a try. Go to /Library/Caches/ folder and remove com.apple.LaunchServices-023501.csstore. See if that helps.

I tried that and it still came back. When I checked /Library/Caches again, the file had reappeared.

Caches will reappear when they are rebuilt. There is another cache associated with the dyld item that appeared in the open files you posted. Below is a fix you might try:

If you see this error in your system logs or in the terminal
"dyld: shared cached file was built against a different libSystem.dylib, ignoring cache"

Open terminal, type in this command, press enter.

sudo update dyld_sharedcache

Type in your admin password when prompted, press enter.

+If you see this error in your system logs or in the terminal+
+"dyld: shared cached file was built against a different libSystem.dylib, ignoring cache"+

when would I see that error?

Did u solve the Problem this way?
'Cause I have exactly the same problem. But typing in the command in the Terminal and confirming it with my password, didn't work out. It still reappears.
Did you maybe solve the problem in the meanwhile?

Hi,

First post and looking for some help on the above too...

I'm receiving a 'open (not responding)' with the following message:

/

/usr/bin/open

/Library/Caches/com.apple.LaunchServices-023501.csstore

/usr/lib/dyld

/private/var/db/dyld/dyld_shared_cache_i386

/dev/null

count=0, state=0x2

Any help would be much appreciated,

Cheers

Hello, & welcome to the forums! 🙂

Could be many things, we should start with this...

"Try Disk Utility

1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.

3. Click the First Aid tab.

4. Select your Mac OS X volume.

5. Click Repair. Disk Utility checks and repairs the disk."

http://docs.info.apple.com/article.html?artnum=106214

Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

If 10.7 or more, reboot holding CMD+r down to boot from the Restore Partition, use Disk Utility there.

BTW, I should mention that it's quite acceptable to start a new topic of your own.

In theory, it should prevent anymore losses & possibly recover some, but that's only 99.95% the case, there are rare instances where sometung could get worse, for instance if we're dealing with a RAM issue, anything you do could scramble it worse.

Hey everybody. I have had exactly this problem and could not find out what was going on. This morning I found out that I had a program SYNCMATE installed. I don't remember installing it but it was making it impossible to autostart/autostop the computer because it popped up a window asking to syncronize.

I deleted SyncMate and now the open (not responding) doesn't exist anymore.

Maybe a coincidence but............

I too had SyncMate installed at one time, but had deleted it. I was also seeing "Open(not responding)" in activity monitor – I installed EtreCheck which shows you all the little addons you have installed and I noticed a kernal extension from SyncMate still being loaded. Removed it and now the "open" process is no longer shown.

I too have the 'open (Not Responding) message in my activity monitor.

I am not very knowlageble in the internal workings of the mac osx. Upon the suggestion of cucocreative i downloaded EtreCheck.

This indicated that I have a number of launch deamons that i know i do not need and one that failed.

How can i remove the fact thes deamons are loaded?

Thanks in advance
