The problem occured only once as now after over 120 days of uptime. The ASA crashed and rebooted suddenly.

There is something interesting in crashinfo file:

- no changes except for regular ACL changes;

- no new hadrware;

- no SSM modules.

I Think the error message that you have provided relates to some ICMP related issue.Try removing "ICMP inspection".Also try upgrading to 7.2.4 as there has been a similar issue with previous versions.Check for available free memory as the ASA may crash due to non-availability of memory.

The entire crash dump is needed to relate it to any known bug or issue. I would suggest opening a TAC case so the crash can be decoded and analyzed. Without doing so, any software upgrade is just a best effort guess.
