The short answer: My original changes to /etc/system were correct, but I
needed to recompile Apache to handle additional filehandles (It is 256 by
default). As of right now I am running with 266 open files, so all appears
to be well.
/etc/system:
set rlim_fd_cur = 1024
Apache:
Re-Compile with extra flag -DFD_SETSIZE=1024
Other notes:
- A number of people suggesting lowering rlim_fd_cur to 1024 as a number of
tuning documents state this is the max
- The default for rlim_fd_max is 1024, so that does not need to be set in
/etc/system
- Another really good suggestion was to add 'ulimit -n unlimited' in my
startup script. This would have taken care of my Solaris filehandles w/out
a reboot.
- About 50 people asked if I had remembered to reboot. Must be more
specific next time ;)
thanks a bunch,
