Thanks to all those who wrote with helpful suggestions, Justin Stringfellow at
Sun cracked it by notifying me that there was a known issue with VTS
generating memory failures on Solaris 8 with certain patchlevels:
"When running SunVTS 4.1, 5.1 with Solaris 8 and kernel update patch
108528-16, you will see error messages of:
FATAL mem: "Unable to read pointer to memlist structure."
Problem Solution
Problem is due to the fact that the symbol "max_ce_err" was deleted from the
kernel with the 108528-16 patch.
Workaround:
Install patch 113689 from http://sunsolve.sun.com
Run with kernel patch 108528-15
Do not run pmemtest with 108528-16 or later."
I solved the problem by 1) updating to SUNWvts 5.1 and its associated packages
2) Installing patch 1113689-10
This summary was a little delayed while I registered with sunsolve to get this
non-public patch. I suppose if you don't have a support contract you would
be obliged either not to run pmemtest (still leaves another memory test
available) or backout to a a kernel patchlevel < 108528-16
Thanks also to Joe Fletcher for reminding me that you need to do cat
/etc/release in order to get the version number, e.g:
$ cat /etc/release
Solaris 8 10/01 s28s_u6wos_08a SPARC

Assembled 12 September 2001
and to David M. Dennis for helpful input about RAM. Please forgive me if I've
missed anyone out, I've been collecting emails on a succession of different
machines. My original query:
In the spirit of hope triumphing over experience, I just wanted to ask if
anyone can see a reason not to call the Sun Doctor (the machine is on Silver
Service) after a stop a few seconds into a run of SunVtS with this error:
04/03/03 15:36:05 server SunVTS4.5: VTSID 8004 pmemtest.
FATAL mem: "Unable to read pointer to memlist structure."
uname -a# SunOS server 5.8 Generic_108528-19 sun4u sparc SUNW,Ultra-5_10
SunVTS version 4.5.
Sun's own docs do seem to tell you to call them out, but I was just hoping
someone knows a reason why the error might be in ... er ... error.
Machine has up-to-date OBP, and is giving no signs of trouble, logs are void
of doom-laden messages. However, since it's done very little work recently
except fit its own recommended patch set, am I inviting trouble by doing
nothing if I should need it soon?
