Hello TC Forum,
As you can indicate, this is my first thread to this forum, pls. be patient with me...

Let me start right now with the essientials:

First let me introduce our environment:

We have a huge vmware installation within an IBM blade center(s).
Effected systems run SLES 11 SP2 with HAE extensions (its acluster with 2 nodes and LVS ldirector with one "virtual IP to the outside)

With this configuration we run a ERP system, based on Springsource TC Server(s) ,several java based modules are building the ERP , backend is a remote Oracle DB Server.

Now the Problem:

Since some weeks we are confrontated with tc crashes, absolute independent from systemload , access time and so on, crashes happens absolute randomly. In the crash logs under /opt/oracle/hs_err.pidxxx.log I always see the following
entry

------# A fatal error has been detected by the Java Runtime Environment:

Believe me, I googled lots of hours , may say days about that problem and messages, what I found didnt really help, there where messages about the deletion of the io.temp by cronjobs, update in java versions and so on...

Actually I dont know how to proceed as I`m not a Java guru , any hints are exreamly welcome

Thanks in Advance !!
