Cisco ASA reboots every 7 days

Kanes Ramasamy

Hi All,

I have an ASA pair which runs in active/standy configuration and below is my problem:

- The standby ASA reloads every 7days once but at different times not the same time.

- Have replaced the ASA twice.

- Have changed the power point and rack as well.

- There is no crash info file on the flash.

Details of the asa is as below:

This may be bug (standby reload) with IOS the device currently running. Check Cisco bug toolkit for any known bugs.




Hi Kaneswaran,

Could you provide with the syslog from standby ASA of the time when reload occurs?
