Hello,

We have heavy-loaded site, and before application server is pound :) It 
has been working good few years, but now we have much more 
traffic(req/s), and we get often 'pound: HTTP accept: Too many open 
files' in the log and 503 to client.
It isn't problem with ulimit because we set high ulimit for nofile, and 
we start pound like this:

/usr/sbin/softlimit -o 16384 /usr/bin/pound -f /etc/pound/pound.cfg

There is also high kernel limit for threads

 > cat /proc/sys/kernel/threads-max
16384
 >

We can only achieve 512 pound threads, and lsof shows 1053 open 
files(pound uses 29 files for itself).
So the limit is 1024, but I don't know where.

Any idea?

Best Regards
Maciej Bogucki
