Controller reboot

Our local controller rebooted on it's own yesterday (this happens occasionally_ and this is what I found on the controller:


Reboot Cause: Datapath timeout (SOS Assert) (Intent:cause:register 54:86:50:2)

Supervisor Card


There is no crash log file. We called TAC a couple of times but with no log there's not much they could do..

Re: Controller reboot

Could this be a AOS 8.x error? fixed in 


163066 Symptom: A managed device rebooted unexpectedly.

The log files for the event listed the reason as Datapath timeout (SOS Assert) (Intent:cause:register 54:86:50:60).


The fix ensures that the
managed device works as expected.
Scenario: This issue was observed in managed devices running
ArubaOS or later versions.

Re: Controller reboot

magnumpi83, the best thing you can do is to put a console cable on the controller and have a PC that captures the output there constantly.  It is entirely possible that there is crash information on the console that would help TAC get to the bottom of it.
