Subject Tomcat thread blocking
Date Wed, 24 Sep 2008 07:37:48 GMT


I've recently observed a scenario in Tomcat 6.0.13 64-bit under SUN JDK
1.6_03 (x64 Windows platform), where a large number of threads show a
status of BLOCKED.


Can someone please advise the easiest and most effective way of helping
identify the original cause of the block?....or have I just opened up a
can of worms?!


The behaviour is not something I can replicate so I need a method for in
situ investigation, before I have to restart Tomcat to restore service
(after a while Tomcat consumes too much CPU and becomes unresponsive)


Any pointers would be much appreciated.
