Getting this error everytime I start a new ZSH session:

/usr/bin/id: fork: Resource temporarily unavailable

Any idea how to fix this? I'm running on Mac OS X Lion and zsh. Let me know if you need any additional details. Not sure when this started, so not sure what could've caused it...

This question came from our site for system and network administrators.

This usually means you have hit the limit on the number of running processes, and cannot start any more.
Note that this may be the system-wide limit, a per-user limit, or a per-session limit. (I believe OS X only has a system-wide limit by default.)

This question over on SuperUser deals with this issue, but basically you need to figure out what has spawned so many processes and make it stop doing that. Sorry I can't be more specific, but it's impossible for someone on Server Fault to tell you what is running on your system.
