Title: RE: QINTER subsystem locking up

This sounds like something that happened to us a few months ago and it took us a week to discover what was going on with the help of IBM and the campus network staff. It turn out that the campus network people had put a patch on our router that our AS/400 didn't like. We had our Ethernet lines configured to recognize IEEE 802.3 and Ethernet Version 2 standards. The AS/400 and the router would negotiate which to use and our AS/400 would always choose IEEE 802.3. The router would agree but then the 400 would start to loose packets in a hurry resulting in sessions being dropped or failing to connect.

I reconfigured the Ethernet line to recognize Ethernet Version 2 only and the problems when away.

Subject: QINTER subsystem locking up

Can someone please wave a magic wand ?

My Qinter subsystem monitor keeps locking, client access sessions won't
start, active sessions hang or drop out; the processor is at 100% normally
so that's no clue. It seems that if I sign on at the console (DSP01 in
QCTL) I can see the joblog of the Qinter sbs mon job, it is nearly always
reporting a combination of CPF1195, CPF4128, CPF5263, CPF5170 messages. I'm
fully up to date with group PTFs and CumPTF level.

I am running a 510-2143, V4R3 system, 768MB memory (*INTERACT has 378000K).
There are no twinax devices, they are all client access and QPADEV* sessions
(160 ish of them).

I have worked on the problem with Assist/400, but other than PTFs, I got no
fix.

Has anyone else experienced this infuriating problem, and got a fix ?

Kind regards,
Jeff Bull.
