SMP and Snap

I had SMP with two Opterons running flawlessly for several months. Then 
very slowly all sorts of problems began occurring. This is from the Snap 
problems.txt
'Running OS/2 with an SMP kernel is not supported.  It may work for you, 
  but there are several reports of odd slowness and/or strange crashes. 
If you experience these kinds of problems, please report the problems to 
IBM, and be sure to open a PMR for it'.
I did a reinstall and so far so good.
It would be nice if Bab StJohn could get IBM to look at the problem.

Which version of SNAP? I have

"Version 3.1.6, build 503
eComstation Special Edition"

The string "SMP" appears nowhere in any of the human-readable files.

It is indeed in the problems.txt file.  However, I am running with 
3.1.7, build 504 on a SMP machine.  I have been running the various SNAP
releases for a long time with SMP (the supported IBM version with 
os2apic.psd).

Where are you finding this bit about problems with SNAP on SMP machines? 
Here is the complete text of the PROBLEMS.TXT file on my system with 
SNAP 3.1.6:

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++********
                     SciTech SNAP Graphics for OS/2
                     ------------------------------

                               KNOWN PROBLEMS
                               --------------

  . Video cards with the Weitek P9000 chipset, that use a BrookTree 485 
RAMDAC (such as the Diamond Viper), have some compatibility problems 
with some motherboards.  Video cards with S3 Vision chipsets, 
particularly those using an S3 SDAC, may also exhibit problems of this 
type.  If you see some vibration of the screen image, you should change 
your refresh rate selection until you find one that is satisfactory.

  . The Kensington mouse drivers are incompatible with third-party GRADD
    driver filters, such as VCAFILT for the WinCast TV cards.

  . Laptops which use the Trident 9397 graphics chipset may not switch
    between LCD and CRT for modes greater than 1024x768.  This is a
    hardware problem, not a driver issue."
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++********

But I think that this file may be left over from an earlier version 
(it's dated 7-26-05). I can find no PROBLEMS.TXT file at all in the 
3.1.6 or 3.1.7 ZIP archives. The most recent post with "SMP" in the 
subject line on the Scitech SNAP OS/2 ng is over a year old and reports 
that the user had encountered no problem. Other messages there referred 
to a new PMMERGE.DLL that was alleged to fix the problems.

I have tried 3.0.0, 3.0.1, 3.1.1, and 3.1.6. I have have problems 
running snapse  485 and 478. Look in the file problem.txt that 
accompanies snap-os2-3.1.6. I am in my 2nd day without problems running 
a fresh install of 1.2r using snapse485 and having removed one the the 
Opterons. It got so bad that programs would not launch from ecenter and 
programs would not even install. I was getting ready to abandon eCS and 
go to a Mac.
