We have two ASA 5520's in active/failover and everyday at this same time (11:00CST) the primary devices indicates it has lost communications with mate on all interfaces. It then tests interfaces which pass and then everything runs normally for 24 hours.
Using ASA 5520 VPN Plus license with asa721-19-k8.bin on both devices.
No logging messages on failover device or switches supporting interfaces.
Anyone seen this before?
