7206 Unexpected exception s, started after IOS upgrade
We have a 7206 in service. We began having a problem every couple of days where the router would crash and require a power cycle to fix the problem. Some people I've spoken to suggest bad ram but this occured immediately after we upgraded from 7200-is-mz.121-8 to 7200-is-mz.121-13a. Unless the newer image pushed the memory usage up beyond levels it ever had reached before (with months in service), I find that to be rather coincidental.
