Hey Guys,
I have a customer with a 7200-G1 acting as an LNS (currently terminating
about 400 PPPoE Sessions). The machine has been locking up and rebooting for
the past week. As shown below this router is running 12.4(15)T1 AdvIP.
Other than upgrading to T3, does anybody have any suggestions on where to
look. I am some what concerned about the Processor memory pool being marked
as corrupted in the show stacks from the last reboot.
Here is from the sh ver:
