Yes I opened TAC case 600966437
Initially, msimon at cisco.com thought it may be related to CSCdu58992. I
thought otherwise since:
a) CSCdu58992 was supposedly fixed prior to 12.2(25)S
b) CSCdu58992 applies to Intel based chipsets on the I/O Module, and
mine has DEC based chipset
I downgraded to 12.2(18)S7, which is really where I want to be anyways,
and I was still seeing the problem.
I think it MAY have been enviromental related. The I/O module was
logging warnings about heat
to the log. 107F it was it.
crashinfo_20050218-053551:17w2d: %ENVM-4-ENVWARN: I/O Cont Outlet
measured at 42C/107F
Whats interesting, is that out of all the 7206's in that cabinet, this
one has to coolest running NPE, which is an
NPE-G1. Yet it had the hottest running I/O module, and not by a little
either, by about 20 degrees!
The ONLY other changes I made, was I removed some basic policy maps
that were put in place to do some LLQ
for voice traffic. I plan to restore those policy maps here real soon.
I honestly think it may have been the heat issue.
Since removing some panels in that cabinet to make some better airflow,
the I/O has been within tolerance, and I have
not had a crash yet.
I did not hear anything back from the DE who was looking over the
crashlog however.
