[Wrapper-user] "JVM appears hung": Wrapper restarts webserver every week

[Andreas K. <and...@ya...>]

Hi wrapper-folks!
I would love some hints and ideas on how to debug this problem and find a solution.

The system is a 
- windows server 2003
- jettyserver
- java 1.4.1
- wrapper 3.0.5

It has been running for years without any problems. But after some updates of the
data in the database where the web-content is stored and a recompile of the code it
started to produce these messages (pasted below). It happens approximately once
every week.
How can I debug this? 
Is there a way to trigg a dump when it happens?
