Description (partial)

Symptom:

7206VXR NPE-G2 running 12.4(24)T that encountered a Software Forced Crash due to Process Watchdog Timeout as indicated below:

---------------------------------------------------------------
Apr 11 14:28:23 EDT: %SYS-3-CPUHOG: Task is running for (126004)msecs, more than
(2000)msecs (87/13),process = encrypt proc.

%Software-forced reload
Conditions:
This only occurs in SW Crypto. Usually, when a customer experiences this, it's because they're running a c7200p router with VAM or VAM2 and upgraded beyond 12.4(15)T. IOS beyond 12.4(15)T no longer supports those HW crypto engines, and will switch the router onto software crypto instead. 

EOL documentation for VAM/VAM2 is found here:
