Re: CPF8907 on STRPASTHR over AnyNet

[Neil Palmer <NeilP@xxxxxxxxxxx>]

Gord - thanks a lot.  That looks very promising.  I'll give it a try and 
report back to the list.  What Keep Alive & Retry values worked for you?

Strangely enough, the document you sent does not seem to be available when 
searching the IBM Knowledge Base:

:-)

We had this problem a year or so ago.  I was sent the following and it has
solved the problem for us.

Hope it helps.
