We're normally configured for active/standby between two ACE modules in two 6500's.
For some odd reason there was a loss between the ft vlan interfaces, and the FT state was flapping between the two ACE's.
I saw all kinds of combination: active/standby-bulk, standby-bulk/active, active/active, and my terminal was filled w/ lines that say config enabled, config disabled...
I think part of the reason they were flapping was because we have preempt enabled.
However, I'd like to find out what caused the communication loss between the two modules.
Has anyone run into this issue before?
