Ok, so not some old software ....

I've tussled with RWAST in the past, but, as the years passed, not so 
much anymore.  More memory seems to be a great help, but I'm guessing.

Maybe old issues have been fixed, or just gone away for the most part. 
But regardless of any remediation, it is my opinion that TCP/IP is a 
sorry piece of software.  VSI even looked at a total replacement.  Not 
sure why they backtracked on that.

Steve mentioned some of the possibilities, but that doesn't help you if 
you don't know which is the culprit.

I have to ask, is the WSDEFAULT resonable?  This is where more isn't 
always better.  Had a customer greatly increase this quota once, then 
wondered why the system was dying.

Keep in mind, VMS will attempt to get you that WSDEFAULT, whether you 
need it or not.  If you do not, then you're spinning wheels to no 
effect, or in the worst case, negative effect.

Not saying that is  the problem.  I've always attempted to analyze 
actual usage, then set some reasonable WSDEFAULT, with VMS adding memory 
to the working set if needed, more so than over allocating.
