ASA5510 keeps resetting itself

[stuart.clarke]

Hi

We have an ASA5510 which keeps resetting itself for no apparent reason. It does this several times a day and I cannot see any pattern to the times etc. I don't believe it is load related as it also happens overnight when very little is going through the device. When it happens the device just drops off the network (all interfaces) and then when it comes back a few minutes later we can see from the system uptime that it has in fact rebooted itself.

I initially thought it was faulty hardware, so I swapped the device for another 5510, but that does the same thing. I then added a third 5510 and configured it in with the second one as an Active/Passive failover pair. Both devices do the same as the first, the only differences now is that the passive device kicks in and takes over, so we have a little less service disruption each time.

Has anybody got any suggestions?

Hi Stuart,

The firewall might be crashing and this may be a software issue, so swapping devices might not help, i would suggest you to kindly take an output of show tceh and show crashinfo and open a TAC case for further investigation.

Thanks,

I tried to open a TAC case but this unit is not covered by our smartnet contract so I could not raise it.

So my suggestion would be, to upgrade the firewall to the letest version in the train, to eliminate any possibility of hitting a bug.
