My default setting was 2048. I changed it to 200,000 for now. I haven't really played with sysctl at all. The only change I've ever made in there was for swappiness.

"Maximal number of TCP sockets not attached to any user file handle, held by system. If this number is exceeded orphaned connections are reset immediately and warning is printed."
So, I'd start by checking the value of tcp_max_orphans (with "cat /proc/sys/net/ipv4/tcp_max_orphans"). The widely distributed sysctl.conf tweaks for Linux relays suggests a value of 262144. I think the default in many distros may be 4096, perhaps too low for an Exit.

If you need help making the sysctl tweaks let me know.
