<font size=2 face="sans-serif">Thanks.Looks like there is a bug already.Need
to verify the versions of the fix though it says it was fixed on 5.2 and
we are on 5.3(unless there some internal dependencies that uses earlier
version)</font>

<br><font size=3>That sounds like a bug I came across a little while back.</font>
<br>
<br><font size=3>A bug in my code, not Drools. ;)</font>
<br>
<br><font size=3>If you create listeners and attach them to a session,
then of course, you need to remove them manually. The session will have
references to them, so they can never be garbage collected. It's
the same with any callback model.</font>
<br>
<br><font size=3>However, if you do find an actual bug, you can raise it
here: </font><a href=https://issues.jboss.org/secure/Dashboard.jspa><font size=3 color=blue><u>https://issues.jboss.org/secure/Dashboard.jspa</u></font></a>
<br>
<br><font size=3>Note that unless you are paying for support from JBoss,
then you won't be getting a patch from them. If they fix the bug, then
it will most likely be available in a later major binary release. And there
will most likely be new bugs in that release. If you want a patch for Drools
(community), you need to get the code and build it yourself.</font>

We are using drools as our rule engine in one of our mission critical application

Recently we have found a very bad memory leak with in the drools that does

This caused our distributed JVM's to grow quite rapidly in and we had to
