Subject RE: Tomcat stops responding
Date Mon, 09 Aug 2004 22:04:13 GMT
Thanks for all the help guys, I think I found the problem.

It appears that after a delay the next attempt to access the database to
sign on with the SingleSignOn valve, using a JDBCRealm, throws
SocketExceptions about a Broken pipe. I think my firewall is resetting the
connection when it does not detect any traffic after 3 hours. I am looking
into how long I should make the timeout, suggestions?

The thread kill and the gc statements helped a lot and I am sure will come
in handy in the future, I opened another thread about why DBCP is not used
for SingleSignOn, check it out if you are interested.

Thanks again,

Keith

I have allocated 256M to the JVM running Tomcat and it has never gone above
25M. I have received no out of memory exceptions. The machine in question
has 2gig of RAM.

Check logs for outofmemory exception. If the log has no exceptions check
your memory usage.

Subject: Tomcat stops responding


After I deploy my application everything immediately works fine, no
problems. Then after some time (haven't narrowed it down yet but it seems to
be several hours) Tomcat stops responding to requests. During this time
there are little to no requests of Tomcat. Does anybody know why this might
be occurring?
 
Thanks in advance,
 
Keith
 
Have you ever noticed that the word 'complaint' and 'compliant' are spelled
almost the same except the transposition of a single letter. I wonder why
that is?
