Hi Peter
Thank you for your input.
We will look into it.
What we are trying to see is what is going on on a netview address space
that sometimes runs out of memory and terminates with an abend. We suspect
that it may be related to open and close of files but we need a way to
check for it.
Best wishes
Jack
