EX4100 becomes unresponsive, loses network

I’m suffering this problem my self as well, checking the logs I always see the same lines:

So that made me think: Is a problem with the Firmware updated or the time set-up? Or is just something normal that happend every time the system is restarted?

By the way, how do you made the UNIT live again? the power button doesn’t work, the arrow key works and i try to press the reset button at the back and didn’t work.

So the only way to make the unit accesible again is unplugging the power cord. Is this the only way?

Do you got a way to replicate the problem? What i mean is can you make the issue happend?

@robot256,

Yeah that is the only way to make it live again. There are some kernel settings that you can tweak that will allow the NAS to detect it has kernel panicked and it will auto reboot.

That was about the best I could get to it being stable. If you scroll up in this thread you will see that I ultimately went with another vendor branded NAS. When I took the drives out of the EX4100 and put in some different drives, and reinitialised the unit, it has not had the issue since. Not sure if you can afford to do so, but you could look at backing up everything and reinitialise it from scratch. You could get lucky.

Cheers,
