I think the following should be sufficient:

- Wireshark trace for the Tomcat instance where the issue was observed
- debug logs for the same Tomcat instance
- fd trace for the same Tomcat instance
- a thread dump of the Java process as soon as practical after the issue

Because you are now using longer lasting connections we may need to look
at a longer period of data to figure out exactly what is happening. To
reduce the amount of data we pass around, if I need more data I'll ask
for it. The important thing is that you keep hold of a copy.
