WebSphere is generating huge files under /opt/IBM/WebSphere6.0/AppServer/profiles/default
heapdump123456.1234567891.phd and
javacore1234567.1234567121.txt
What could be the reason for this. Because of this /opt/IBM is becoming 100% full and DataStage application is hanging.

Write jobs that don't abort and therefore don't need to dump memory images.

We have the same issue. From my first investigations this is not related to any aborting jobs. It may be related to connector meta data import...

You may try to increase the max heap memory for the JVM running inside websphere to something like 1596 (from 1024)

What ever happened to Bill Gates' famous dictum "you will never need more than 640 Kbytes of real memory"?

Thanks for your responses.
Is it something related to aborted job warnings. If so, do we need to restrict those warnings. Some times job aborts due to some reasons, it is common in unit testing. What is the remedy for this.

We don't think memory is the issue. This started after installing the Metadata Workbench. Ofcourse nobody is using Metadata Work bench. Any clue...

Un-install of Metadata Workbenck resolved the issue. But, no clue on why Metadata workbench is the cause for this issue.

In that case what gave you the clue to uninstall Metadata Workbench?
What does your official support provider have to say?
