Recently I'm finding that some Mac OS X applications are crashing frequently with backtraces like the following:

Any ideas about what might be causing this and/or how to remedy it?

Given that Google doesn't know much about that error message could be a very bad sign. Have you recently installed kernel extensions, third party device drivers, etc.? I'd probably reinstall Mac OS X. –  Daniel Beck Jan 13 '11 at 6:27
    
Thanks for the input, Daniel. I don't think I've recently installed kexts or drivers on this system. But I have been using this user profile for many years and across several systems... –  smokris Jan 14 '11 at 2:53

I'm not a kernel programmer, but I'm guessing that message has something to do with running out of Mach ports in the kernel. Do you have a zillion processes running, or are you doing a lot of inter-process communication? Are you possibly low on memory and disk space (no room to expand your swap)?

Try using top or Activity Monitor to see if you have any processes going crazy, like perhaps you've written a recursive AppleScript or shell script that's spawning zillions of child processes (like an accidental "fork bomb").

Pay attention to what apps you have running when you hit this crash. Maybe there's an app that overuses Mach ports and sometimes gobbles them all up. Is this problem more likely to hit when you're running a virtual machine system such as VMware, Parallels, or VirtualBox?

In Activity Monitor, I turned on the "Ports" column, and noticed the (third-party) Mozy backup process had allocated tens of thousands of ports and was slowly increasing. I've disabled this application for now. –  smokris May 17 '11 at 17:18

Hmm. I tried resetting SyncServices --- http://support.apple.com/kb/TS1627 --- and Mail hasn't crashed since then.

And a few days later it's crashing again. That apparently didn't fix it. –  smokris Jan 16 '11 at 16:35
