fork failed: resource temp. unavailable - What resource??

[Alexandre W. Agostini_1]

Hi folks!

My application is getting this error, from time to time:
fork() failed:
resource temporarily unavailable

Is there a simple way :) to figure out what resource might have been unavailable at the time of the error?

Thanks already!

If you have Glance (and you really should) you can take a look at the System Tables Report and it will show you the current and highest usage for nproc, nfile, shmmni, msgmni, semmni, nflocks, npty, and nbuf, as well as shared memory, message buffers, inode cache, DNLC cache, buffer cache, and swap space. That would narrow it down almost instantly.

Man 2 fork and you will find there are two possible reasons for errno to be set to EAGAIN nproc - system wide number of processes limit and maxuprc - per user process limit.
