Re: FWSM issue

it'll happens if both FWSM dont see each other on enough monitored vlans as
per the defined threshold, but both sides have their vlans UP....link issues
on inter-chassis trunk, vlan missing on trunk, congestion etc. are the major
reasons..

secondly, it may happen if there is a configuration issue or congestion on
the failover/stateful link...its recommended to use separate links/vlans for
FO and stateful replication to avoid congestion.

use firewall autostate messages to optimize failover timing.

search the CCO for split brain situation, you should find few official
recommendations.
