hi,i'm seeing a strange 'too many open files' error with nginx (which I'm
sure many of you have seen before):
2008/11/17 02:15:02 [alert] 21748#0: accept() failed (24: Too many open
files) while accepting new connection on 18.104.22.168:80
strangely enough, I have the following line in /etc/security/limits:
* hard nofile 524288
and ulimit -n returns the same number. I have 2 workers set to a max
of 262144 connections. upon receiving that error (and after
past occurrences) I've run lsof and gotten < 10k sockets. additionally, I
have a nearly identically configured machine (running twisted) where each
process is handling ~15k connections. so I'm a loss as to what's going on
here (and suspect some subtle bug in nginx or in my server configuration.
any help would be greatly appreciated!
