I've got an ASA 5550 that is performing loads and loads of operations (AnyConnect, NAT, ACL, RADIUS, etc, etc). It isn't particularly overloaded in terms of CPU & Memory, but it has an uptime of over 3.5 years.
Lately I have been attempting to deploy another IPSEC tunnel (via cryptomap) along with a NAT Exempt rule, but the ASA is exhibiting very strange behaviour. Sometimes when I add ACE's a mass of text pops up from nowhere in the description field. No matter what I do, my tests with the on-box PacketTracer tool do not yield the results I expect (for example - I see the packet hitting the Any/Any rule at the bottom of the ACL, even though there is a specifically configured ACE at the top of said ACL).
Anyway, the question is this: Has anyone ever actually solved anything by rebooting an ASA? It isn't my favourite option, but with the very strange behaviours I am seeing troubleshooting is becoming fruitless.
