ASA Failover down

Hello,

For 3 weeks, we have our ASA (configured in failover active / standby) which stops working. When it happens, we have to restart them electrically.
After which, it works for 2 or 3 days, and it starts again. The ASAs are unreachable

When this happens, the LED turns green on the 2 asa.

Re: ASA Failover down

Have you checked console access when the units are unresponsive? Also, check "show failover history" if you can get the output before doing a power cycle.

Re: ASA Failover down

Hello,

 

the unit crashes approximately between 2 a.m. and 2:30 a.m.

when i get to work at 8am i have to restart them quickly.

This night, the problem occures. But it was a little bit different. The standby ASA become primary, but the primary fail. 

 

when I try to connect to the console port access  directly on the faulty ASA, The system is inaccessible.

 

So the connection continues to work but with only one asa

 

 

when i do a #sh failover history
