I suspect you've reached some kind of maximum session count; either in Linux or in netfilter. I expect you can alter this using sysctl, or writing directly to /proc, but unhelpfully I can't see where this is specifically set. It might help others solve your problem if you post the result of iptstate -s -t | head here. Or try wc -l /proc/net/ip_conntrack if "iptstate" isn't installed. Though I'm not *that* familiar with the contents of ip_conntrack, someone may way to advise on a filter that will only show the relevant connections. -- mors omnia vincit
