Filipe:
Thanks for the information.
If I do: cat /proc/sys/net/ipv4/netfilter/ip_conntrack_max on each of my servers, they all report 65536 which seems like a pretty high limit.
If I do: cat /proc/sys/net/ipv4/netfilter/ip_conntrack_count on each of my servers, the highest number is just over 1100.
If this is the source of the problem, how would restarting httpd and tomcat help? I did not restart the machine nor reset iptables.
I am not asking this to be argumentative, just trying to understand how the facts I am seeing are related.
Thanks, Neil

If you're using ESTABLISHED, it depends on ip_conntrack being able to track the connections. ip_conntrack keeps a table of all connections, but this table is limited in size, so it may be overflowing.
