Hi Thanks for your comments.

We haven't used AJP13 since mod_webapp is the supposed to be the preferred method with TC 4.0.1. We used AJP12 with TC 3.2.3 and set the parameters as you show. We still got the same problems so we're not overconfident that AJP13 will fix them. Interesting to read what you say about the restarts - I'll try restarting TC with no Apache restarts. On the session timeout, I have that set to 10 minutes (from the default 30). If there is one thread per session then maybe I ought to go to 5 minutes or less ! Where is the parameter that govens how often the session are checked. In Apache JServ, I recall something like checkInterval in the zone.properties file. Maybe TC4 is cleverer onthat one.
