Not really sure + the whole stacktrace of the original exception is
getting hidden...
But, try creating your own WebRequestServicePipelineBridge
(original is
https://svn.apache.org/repos/asf/tapestry/tapestry4/branches/4.0/framework/src/java/org/apache/tapestry/services/impl/WebRequestServicerPipelineBridge.java
)
and override tapestry.request.WebRequestServicerPipelineBridge service
with your version
(original definition at
https://svn.apache.org/repos/asf/tapestry/tapestry4/branches/4.0/framework/src/descriptor/META-INF/tapestry.request.xml
)
Then, add more logging perhaps to the line that interests you...

Hi all,
I've been running a Tapestry 4.0.2 web application in our production
environment for some months without any major hiccups; until recently
when our Tomcat servers began to crash suddenly and unexpectedly.
After some investigation it seems that amongst the last things to
happen before the server goes down is I get the stack trace below in
catalina.out.
The source code for WebRequestServicePipelineBridge line 60 calls
service() on a WebRequestServicer object; but I don't know how to
debug this further.
We're using Tomcat 5.5.20 and Tapestry 4.0.2.
Any ideas?
