A few off-net replies let me know that attachments don't work on this
list, but I will provide them off list if anyone is willing to help.

Hello,
In the past two weeks, we've had 4 different UBR10Ks with PRE4s crash
for unknown reasons. They're all on 12.2(33)SCG6, and have been with
no issues for about two years. We didn't make any configuration
changes, or push any new features leading up to this, they just seemed
to happen out of nowhere.
I've attached running-configs and crash-logs from 3 of the CMTS'. Also
I managed, to get a 'show stack' from one of them because it has
redundant PREs and wasn't cold rebooted.
Some additional background - We contract with a third party for our
CMTS/Modem NMS that our CSRs use. It's mostly SNMP. based, but they do
have limited read-only ssh access to screen-scrap a few things. I only
say this because maybe they started using a different command that
exposed some bug. This is completely grasping at straws, but it's the
only thing I could think of that may have changed.
Anyway, has anyone had similar issues with this version of IOS or any
version with a PRE4 for that matter? Any experience with a show
command that crashed the PRE and if so what command was it? If anyone
can find anything significant from the logs/configs I attached that
would be amazing, I've been banging my head against this for the past
couple weeks.
Let me know if you need more information.
