3.2(14) 4.0(7)

Description (partial)

If two FWSM's are configured in failover and Active/Active mode and running version 3.2(14) or 4.0(7), FTP transactions through the Firewall might consistently fail.

To hit this bug the following conditions must all be met:

1) The FWSM's must be configured for active/active failover mode
2) The FTP traffic must traverse two contexts
3) The two contexts are not active on the same blade (meaning that one of the contexts is active on the Primary firewall, and the other context is active on the Secondary firewall).
4) The FWSMs must be running the exact versions 3.2(14) or 4.0(7). Versions previous to these, or versions subsequent to these, are not affected.
