Why are you whining, then? ;-)

Subject:        Re: Update on z/VM 5.2.0 problem

We've only had 1 problem to date on our very busy (overloaded :) z9-109
2 engine, 80 linux machine and we've had 5.2.0 there since 1/21.

We had MPROUTE hang last week.  It was due to *something* in our network
which caused our MTU to change and MPROUTE to hang.  Workaround fix
(before PK20644 closes) is to code MTU on the LINK statements (instead
of just in the MPROUTE CONFIG) and to apply:

(just 2 of those weren't on my 5.2.0 system with rsu 501).


Apparently, this is also a 5.1.0 problem too - we just haven't seen it
on our 5.1.0 systems.

Other than that bad day, everything's been chugging right along (and
performing very nicely).

(Operations commented that a "bad switch" in the network caused problems
on lots of things - that was as much as I've been able to find out).

Alyce, what you aren't hearing about are all the sites that have z/VM
5.2 
running with *no* problems; as stable as previous releases.  Yes, there 
are a *few* sites that are having stability problems, but we are 
addressing them rapidly and with good results.

So at this point, no, we have no plan to extend service for z/VM 4.4,
but 
it is an interesting idea in any event, and it's something we'll think 
more about.
