Switch in stack keeps resetting

Switch in stack keeps resetting

I have a stack with 5 x450e-48p switches. Back in January I replaced slot 3 due to it failing and all was good after that. A couple weeks ago slot 3 failed again so I replaced the switch and all was good until this past Friday when it started randomly resetting itself. I don't want to replace the switch again as I don't know if that is the issue. Could a bad stacking cable or module cause this? It is running on an older firmware of 12.4.1.7, could that be causing it?

I have upgraded the XOS to the version stated above but slot 3 keeps failing and resetting. It states it lost communication with the master node. Could this be a stacking cable issue or stacking port issue?

Here is a screenshot of the stacking-port utilization. It clearly shows very little traffic on ports 3:2 & 4:1

Hi DH,
It might be best for you to open a case with GTAC so the team can dig a little deeper to see what might be happening to your stack.
