ERPOE-5 Occasionally Reboots itself by NMI watchdog

Hello!

 

I have just bought two ERPoe-5 routers and one of them reboots itself after ~8-48h (both running EdgeMax v1.6.0). I have captured the diagnostic output from the console port and the reboot is triggered by the NMI watchdog (see info below).

Is this S/W or H/W related? If S/W, why is only some units affected by the problem?

 

How is this fixed?

 

 

Best Regards,

Re: ERPOE-5 Occasionally Reboots itself by NMI watchdog

Unit has now been running for almost 5 days without rebooting so v1.7.0alpha2 seems to rectify this “NMI Watchdog reboot issue”.

 

Does anyone have info on when this fix will be available in an official F/W release?

Re: ERPOE-5 Occasionally Reboots itself by NMI watchdog

Thanks Mr. Bond! :-)

 

I will try the beta release, seems this solved the issue for others with the same problem.

 

As I see it this is a critical defect in the software. Does anyone know when an official release with the fix implemented will be available?
