ASA 5510 seems to work normaly but it restarts itself a dozen times a day. Does anyone have an idea what might cause this?
It is connected to an UPS so power failure should not be the cause. I found some info on the internet that inspect esmtp might cause this. It was removed from the configuration but nothing changed.
The software version is: Cisco Adaptive Security Appliance Software Version 7.2(3) Device Manager Version 5.2(3)
CPU and memory usage are also within normal.
It is a standalone unit (not configured in failover).
