Actually, modern glibc and the Linux kernel imposes no hard FD_SETSIZE limits. They can be raised from the shell using ulimit.
But you might be right about that being Edwards problem--Linux defaults to 1024. Try adding a line like this to your Oops startup script: ulimit -HSn 8192 BTW-FD is file descriptors, not sockets--related but not the same thing. Network sockets (user ports actually) are increased by modifying the values in /proc/sys/net/ipv4/ip_local_port_range. I use the following to set this on all of my Squid boxes: echo 1024 32768 > /proc/sys/net/ipv4/ip_local_port_range Actually, I'll just post the whole limits raising part of my Squid init file--it might be useful: # More file descriptors ulimit -HSn 8192 echo 8192 > /proc/sys/fs/file-max # More user ports for squid to use echo 1024 32768 > /proc/sys/net/ipv4/ip_local_port_range echo 3072 > /proc/sys/net/ipv4/tcp_max_syn_backlog Let us know what you find out, Edward. Actually, now that I'm thinking of it, Oops might look very different to the OS than Squid. Because the file descriptor limit is a per-process limit, it may not hit Oops at all--because each thread is a 'Light Weight Process'...I don't know if a thread is limited by it's parent file descriptor limits.
