------- Additional Comments From markt@apache.org  2008-01-07 16:08 -------
There have been a number of memory leaks, the most recent one logging related,
fixed within Tomcat. There have also been changes to a libraries such as
commons-logging to better handle the multi-classloader environment of a J2EE
server. This fixes/changes will all help.

By default, org.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES
is true which should work around most of the remaining issues.

I would much rather fix a specific issue than add more workarounds that are
likely to cause just as many problems as they set out to solve (threads are per
connector, not per context, would need to handle long running threads in other
contexts etc)

I you have a test case that demonstrates a memory leak with the latest stable
6.0.x release, please feel free to open a new issue, attach the test case and I
will take a look.
