Subject: Re: [cas-dev] Spring webflow exceptions running 3.5.2 on Tomcat
Hi,
Those are just effect, not the cause itself. The real reason is elsewhere. From
those stack traces I may assume that your CAS may be overload or processing
some requests longer than usual. When server is busy, processing something and
client tries to refresh, or open another site the connection is broken and you
may observe "java.lang.IllegalStateException: Cannot create a session after the
response has been committed"
Please create few thread dumps and analyse long running threads. You may use
such script to do so:
for i in {1..10} do; kill -3 $(ps -efww|grep [j]ava| awk '{print $2}'); sleep
5; done
It takes thread dump and wait for 5 seconds, after it it takes another
threaddump and waits for another 5 seconds... Taking summary 10 thread dumps.
Thread dumps are written to standard output (console, or where application
server writes console output).
Only knowing what the application is currently doing may solve your issue, and
that may be in thread dumps.
Hope it helps.

I have also posted this to cas-users but I think you guys might have more
experience with this type of issue. Sorry for the cross-post.
In our localhost log file we occasionally get into a state where we get large
occurrences of these 2 errors:
SEVERE: Servlet.service() for servlet [cas] in context with path [/cas] threw
exception [Request processing failed; nested exception is
java.lang.IllegalStateException: Ca
nnot create a session after the response has been committed] with root cause
java.lang.IllegalStateException: Cannot create a session after the response has
been committed
And:
SEVERE: Servlet.service() for servlet [cas] in context with path [/cas] threw
exception [Request processing failed; nested exception is
org.springframework.webflow.conversation.impl.LockTimeoutException: Unable to
acquire conversation lock after 30 seconds] with root cause
org.springframework.webflow.conversation.impl.LockTimeoutException: Unable to
acquire conversation lock after 30 seconds
Has anyone seen this before. This causes our CASified Peoplesoft portal to
become unstable. It usually takes several days of activity before this occurs.
Thanks
