Hi Patrick

i have this problem before. The main cause is insufficient memory, because my machine and os are 64 bit so i need to allocate at least 2 GB memory for Java stack and solve my problem.

additional node not always can help if you memory doesn't enough it will even worst.

Best Regards

HI Patrik

Check for the trace as said above

I think the connection would be lost and restart due to overlaod of the server.

To resolve this you need to add additional server node in config tool

Config tool -> server ->add server -

this will add the server node and then restart both the stacks

Refer for JVM settings Note 723909

Hi Patrick!

Look into defaultTrace.trc trace file. This is the "heart beat" trace file of the J2EE engine.

In general you may have memory problems in your J2EE stack. This very often is the root cause for "automatic" restarts of J2EE Engine.
