I am running tsm on mvs. If this happened to me, I would
take an svc dump and open a pmr with IBM. TSM keeps
running, the dump process doesn't crash it.
But I am in the process of rehosting to solaris. I have 2 questions,
first how would I get the same type of dump on solaris, & second,
has anyone with this problem gotten a dump and reported it to IBM?
It sounds like a bug to me and IBM won't fix it if they don't
know about it.
