I've upgrade my unraid server from a very oldIBM x3200 M3 server to new hardware (Intel 245k base). Since then the system become very unstable. The server GUI will become very slow / not responding after a while. I can still ping the server but I am not able to ssh to it anymore. I've ran a memtest the test result is passed. I've also change the docker to using IPVLAN (previously MACVLAN). However it is still the same. Attached diagnostics file.
