In scenarios where there are multiple slots on a chassis in an HA pair (in both vCMP and chassis only mode), the error "Access Policy configuration has changed on gateway" might be displayed when a user connects to a virtual server.
Customer would see following message when they connect to virtual server "Access Policy configuration has changed on gateway"
It can occur in conditions when : - right after when the whole chassis is rebooted - secondary/slave slot's tmm cores. - disabling a slot on chassis
To work around the problem, type the command "bigstart restart apd" on the primary slot.
The issue is fixed by having the primary blade of the chassis/vCMP to recreate config snapshots if a secondary blade transitions from online to offline and vice versa.
