Unexpected exception to CPUvector 1400 problem on route 1811

Hello ,

=== Start of Crashinfo Collection (11:17:06 PCTime Wed Jan 24 2007) ===

First i want to ask what means problem in CPUvector 1400 because i searched it int the net but with no results for now.

I think that upgrade to higher version will solve the problem , but the funny thing here is that i have 11 router like the one with the rebooting problem. They are all configured in same configuration, IOS version , modules ,etc

like the rebooting router and everything it's ok with them.

I think the following info is needed

Router 1811

Cisco IOS Software, C181X Software (C181X-ADVIPSERVICESK9-M), Version 12.4(2)T1,

RELEASE SOFTWARE (fc3

ROM: System Bootstrap, Version 12.3(8r)YH5, RELEASE SOFTWARE (fc1)

System image file is "flash:c181x-advipservicesk9-mz.124-2.T1.bin"

Thanks in advance :)

You are hitting the bug :CSCsa79340. Upgrade IOS to 12.4(4)T1 would fix the bug.

Thnaks for the perfect answer. According to the CSCsa79340 bug i found another forum post saying a problem like mine. There is memory leak after specific amount of denys ACL was logged , causing router reload wich is exactly my case. I'll try stop logging for the current ACL and test , or upgrade to the 12.4(4)T1 . Thanks again for the troubleshooting ;-)
