Tomcat 5 Memory Leak

Tomcat 5 Memory Leak

Hi,

  Our java based application is running on tomcat 5.0.3 on linux with JRE
1.4.2_08.
  Since the migration from tomcat 5.0.27 to 5.0.30, a bunch of our
application's sessions are not correctly closed and so they stay in live
using memory.
  In using a leak tracker tool, a memory leak has been found in
org.apache.tomcat.util.threads.ThreadWithAttributes Source code of org.apache.tomcat.util.threads.ThreadWithAttributes
  I have found some information about this issue dealing with swallowOutput
however the application doesn't use it and that doesn't correspond to our
exact tomcat version.

(http://mail-archives.apache.org/mod_mbox/tomcat-users/200502.mbox/%3CBAY16-
F173DE50AF5D24443CD3874E17E0@(protected)%3E)   Unfortunately at this time we
don't have any more detail about it.

  Can somebody help?

  Denis B.
