Cisco ASA 5516 Blocking all traffic, works after reboot

We have 2 ASA 5516 w/firepower setup in Active/Passive mode.  Every 2 days or so the firewalls become inaccessible. We cant get to them internally, internet access is blocked and all incoming VPN traffic is blocked.  If we reboot the firewalls they come back online and everything works as normal for another 2-3 days then same issue again.

Re: Cisco ASA 5516 Blocking all traffic, works after reboot

it was noted some time back with the user that - the Logging enables was over killing the performance and some time device un responsive-  if this is your case please disable Logging and check, if the trick works.

 

we do have FTD 4XXX / FMC - full Logging enables kill the network.

Re: Cisco ASA 5516 Blocking all traffic, works after reboot

another thing i can think of was box might have overloaded

when the traffic stops.

 

check NAT, also check CPU, check the Logs and post the information here.

 

what version of code running here?
