> We're running into some issues hitting FD limits, mostly running Websphere on RH5.5.
> 
> We've been able to raise the limit by adding entries to /etc/security/limits.conf for the user running Websphere, but still don't fully understand how the kernel counts how many FDs a user has open (websphere is the only thing running java but lsof -c /java/ | wc -l sometimes shows a value over the limit w/ no obv issues), if that is the right place to set it, and where the default of 1024 comes from?
> 
> Further confusing it for me at least is that ulimit is a bash builtin command, but the limits are enforced by the kernel?
> 
> Any insight would be helpful.
