Not sure if this is the right place for this, but my mac (mountain lion) has recently started crashing suddenly. Below is the error I get on restarting. Am I correct in assuming the issue is vim?

Nope, I use MacVIM all the time. Your issue is somewhere else. –  Richard Brown Apr 23 '13 at 19:06
Vim is very stable here as well. If you are moderately certain it is a Vim issue, the vim-mac mailing list is a more appropriate place. –  romainl Apr 23 '13 at 19:21
I agree I've been using vim for 8 years and never had problems. What to make of the "BSD process name corresponding to current thread: Vim" then? –  pixelearth Apr 23 '13 at 19:25
@pixelearth Seems many have had this issue when using tmux. If you're using that, see if you can repeat the problem without it. –  Joachim Isaksson Apr 23 '13 at 20:45
You know I too have the same problem suddenly cropping up. Yesterday, My Mac crashed as I was in a MacVIM Diff session. Then, today it happened again. Of course, I use MacVIM quite a bit in my job, so it may simply be coincidence that it was active when it happened. Apparently, there is some issue with MacVIM causing panics, and this is the second time I've seen tmux mentioned. –  David W. Sep 17 '13 at 19:03

No the issue is probably not vim.

The crash report indicate the OS X kernel (xnu) crashed when vim was the current active process, but it's not necessarily vim that made the system crash. Actually vim is quite stable and run in user-space, so it's very unlikely that it made your system crash.

Note: By active, I do not mean front-most. For the multi-tasking to work, the kernel gives CPU time to all processes alternatively, switching fast enough to give the impression that all of the processes run “at the same time”. At the time of your crash, vim was the current process with CPU time.

How would I go about finding out what the issue is? It happens about once a week or so, always with VIM as the current process... –  pixelearth Apr 24 '13 at 8:18
There are many possible causes for a kernel panic, most of them being a hardware (often memory) failure, or bogus kernel extensions. I would first recommend running the Apple Hardware Test (keep D down at boot to launch), perform Disk Checks and repairing permissions. If panics persist, try the links listed here: discussions.apple.com/thread/2722164?start=0&tstart=0 –  Frizlab Apr 24 '13 at 11:57

This seems to be an issue that is covered under Apple TS4088 regarding spontaneous crashes, especially on mid-2010 MBPs. Worth investigating.
