  2012/11/04 20:13:35 [alert] 1080#0: accept4() failed (24: Too many open files)

  i.e: ulimit -n 9999

  But definitely weird, since that would mean that there are more than 1000 concurrent connections on nginx

  [04-Nov-2012 22:31:19] WARNING: [pool www] seems busy (you may need to increase start_servers, or min/max_spare_servers), spawning 16 children, there are 0 idle, and 14 total children

  Pretty simple solution by just increasing the count of php-fpm childrens

  By the way: I'm going to bed at 23:00, so if you need some urgent help, try to reach me on IRC

  Your Linux ulimits are set too low. You'll need to adjust worker_rlimit_nofile, the nginx directive, too.

  Here's a nice tutorial explaining it all to you: http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/

  @tinyray Nope, what Amfy and I said

  That said, I can't help but wonder /something/ about your post...

  Thanks, havent done it yet as that error only occurred at 20:13:35 yesterday and went away after that.

  I did increase that setting, thanks, stupid from me not to think of that.

  I went to sleep after increasing too, will you be on IRC end of the day (after work/school) ?
