We have some problems with 2 Cisco ASA 5540. One of these 2 ASA is Active and another is Standby.
We are doing some tests, we try to shutdown the active ASA and Standby takes over, but there is around 650 ipsec vpn clients that connects at the same time on to Standby because Active is down, so the standby ASA gets 100% on CPU usage during this and only around 150 ipsec clients gets connected the rest is not possible.... to connect and cpu hangs on 100% because the rest is trying to connect....
Any idea what we can do in this case ??
