I'm running some stress test on the NanoPi neo2 512mb, CPU heating reached 75-76 degrees, and it's stable, the problem that I faced is that the computer changed it's IP suddenly (after 55 minutes of test running), I guess it's because of a network card reset.
In a deferent event, the network was disconnected and reconnected...

Did anyone face the following issue? Is it related to the stress test? Or it's another networking problem?

The test I'm running is with the "stress" tool, running long time stress on 4 CPUs.

OS installed: Armbian latest stretch version
