Resource temporarily unavailable! Errors
 

[24.209.61.197:3871-0#mustangevolution] connection to [/tmp/lshttpd/lsphp5.sock.665] on request #0, confirmed, 0, associated process: 26033, running: 1, error: Resource temporarily unavailable!


I have a ton of these errors in my server log, along with errors such as [24.209.61.197:3865-0#mustangevolution] External processor is not available.

Any idea on what I can do to get rid of these errors?

You need to increase the per process file descriptor limit
