Hello All,
Thank you for the suggestions.
We noted that we have these errors in the logs -
SEVERE: The web application [/rel] registered the JBDC driver
[oracle.jdbc.OracleDriver] but failed to unregister it when the web
application was stopped. To prevent a memory leak, the JDBC Driver has been
forcibly unregistered.

clearReferencesThreads
SEVERE: The web application [/rel] appears to have started a thread named
[Thread-7] but has failed to stop it. This is very likely to create a memory
leak.
Dec 21, 2010 1:41:48 AM org.apache.catalina.loader.WebappClassLoader
clearThreadLocalMap
SEVERE: The web application [/rel] created a ThreadLocal with key of type
[org.apache.commons.lang.builder.ReflectionToStringBuilder$1] (value
[org.apache.commons.lang.builder.reflectiontostringbuilde...@29fb93]) and a
value of type [java.util.HashSet] (value [[]]) but failed to remove it when
the web application was stopped. This is very likely to create a memory
leak.
The thread dump has been attached with this mail.
Hope these help.
We are now trying to replicate this issue by running tomcat on port 80
(switching off apache httpd).
I'll post the observations here after we do this.
Thanks again
Sreekumar
