What is the limit on ip_conntrack_max?  Can I increase it more?  How can I resolve teh problem of the table being full?

You can increase it easily (echo a-huge-number > /proc/sys/net/ipv4/netfilter/ip_conntrack_max), but a better way using the almost-unknown hashsize option of ip_conntrack module:

We had the same issue and the solutions above helped.
