RE: Rising number of connections

Have you perhaps incorrectly configured your SNMP tool to graph the value as a gauge instead of a counter (I assume that the SNMP module returns counters)? That would produce a continuously increasing graph.

As to the old processes still running there were some bugs that caused this issue which have now been resolved. I can't find the specific version that this bug is resolved in, but I have been affected by it in the past.

As Joseph asks, what version and OS?
