You are correct. I was working off his version. Sometimes "upgrade" is not
an option even though it's the easiest answer so I was working with what I
had.

Charles this is a known bug, and was fixed in later FWSM versions (only
happens no reboot).

We faced it once too and learned it the same (hard) way :)

Fahad, please see 'show failover history' to know more about the reason
for the last failover (on both devices). It does not always help, but
still...

  I have also seen where the VLANs applied to the MSFC via the svclc group
  (or firewall vlan-group) do not get passed up to the FWSM. Say VLAN 11 is

  and the FWSM in chassis2 have different VLANs. This can cause them to
  fail
  to sync and both go active. Learned this the hard way....

  Here are some troubleshooting steps:

  1- Make sure both FWSM must have same software version, license and in
  the same routed or transparent mode.

  2- Same Vlans should be allowed on both FWSM trunks.

  3- Enable "monitor-interface" on all interfaces.

  Did you see any logs when both FWSM became Active/Active?

  Regards,
  Anser
