How to know the cause for abend/core files generation?
My research says that either infinite looping/retrieving large volumes from DB/less memory availbility might be the reasons.
My problem is ,
Abend files are being generated v.rarely and not regularly. only for 1 out of 10 messages , abend file is being generated.
Am not knowing when its being generated and unable to recreate the problem(abend file) too..
How shall i resolve the problem ??
how come abend files are generated on irregular basis??.. If the flow has something that is really really bad , abend file has to be generated each and then when i run the flow but this is not happening!! !

So it doesn't run out of memory all the time. A common scenario (not an WMB one) is the memory leak, which doesn't manifest as a problem until after a period of runtime.

Not saying that's your problem, but one explaination of why it doesn't always happen, and doesn't happen when you try it in isolation.

Also abend files for 1 out of 10 messages is much more frequent than I'd be happy with. You either have some dubious code, or an envrionment problem.
