Hi,


typically, is a software crash. With patience, one could get to a specific reason or bug, however it is recommended that you upgrade to the latest maintenance releaseof the version you are running. Chances are it won't happen anymore.


Hope this helps, please rate post if it does!

Actually you are already running the latest version of 12.4(2)T. At this point, to eliminate blind upgrades, either you go to the TAC to find what caused the crash, or do yourself using 'output interpreter'.


Since both things require a support contract, If you can't do the above, post here output of show stacks | begin Crashinfo
