Hello,
This isn't a lab problem, but a real-world issue. I've got three ASA 5520s where one is the central peer (Hub) and the other two are my distant ends (Spokes). About once every 6-7 months the Hub and spokes will encounter an issue where they all rekey at the exact same time and get stuck in an MM_WAIT_MSG state until a clear crypto isakmp sa is applied on both ends. This is a problem since the spoke (distant end) is unreachable because it is stuck waiting on a rekey completion from the hub ASA.
Why does this happen and why hasn't Cisco addressed the issue with a timeout? Also, how can I go about resolving the issue?

I'm not near the devices at the moment, but I believe it is 8.2.4 K8. Whichever is the more current FIPS approved IOS.CompTIA: Net+, Sec+
