Thanks for the reply, I was mainly asking about tracking down why connections are going unanswered by ASSP when the OS has already seen them and iptables has logged them. I have connection debug set to highest and nothing shows up relating to these connections.
Is there any condition under which ASSP will hit a limit and not log message stating so? The socket poll logs were something I saw in the logs maybe 20 times a day whilst trying to find something relating to the first issue. Most of the socket poll logs come from workers not the main thread and the system load is quite low. CPU usage is less than 20% at peak and the load only gets up to 3 on an 8 core CPU which is a little over 25%. I did increase to 12 cores to see if extra power would help but it didn't.
