Web application server memory collapsed

Hi! I'm having the same problem again and again and I don't know why... It happens that a proeccess called java.exe increases more and more in my web application server (where DA and webtop are located) until the memory is collapsed and both da and webtop stup working. I restart the system, but in a while I get the same issue again. Looking at my log4j.log I see the following error:

[DM_DOCBROKER_E_NO_SERVERS_FOR_DOCBASE]error: "The DocBroker running on host (xdctmcs:1489) does not know of a server for the specified docbase (LagunAro)"; ERRORCODE: 100; NEXT: null

But the thing is that just a week ago this problem didn't exist, and I have not made any changes in any configuration file sucha as dfc.properties, server.ini....

Which can be the origin of the problem? I've read that it could be related to the DfClientX treatment in my code, but after checking it I'm sure it isn't...

Any idea would be grateful!

What version of app server are you using and what version of JRE? Also, what version of DA are you using?

My app server is jboss4.2.0, the jre version is 1.5.0_12, and both da and webtop are 6.5 sp1

Webtop 6.5 SP1 release notes states that only jboss 4.2.3 is supported.

Yes you're right, it was a typing mistake, my jboss version is 4.2.3...

Did you follow the pre-deployment instructions for your specific app server? Each app server requires specific changes before you can deploy WAR file.

Yes, it was installed 3 years ago and has never given this problem. I've seen in the server log an error related to the garbage collector: [DFC_SESSION_NOT_RELEASED] Unreleased session found during garbage collection, Session. Would it be related to my problem?

Typically, if a problem suddenly arises (without any code change), that its normally something in the environment that has changed. Sometimes has to do with Java being automatically updated or possible app server getting patched.
