System keeps freezing

Hello all

I've been having issues with my Unraid 6.1.9 VM for a couple of days now. My box experienced an unexpected power failure several days ago and my Unraid VM has been freezing every couple of hours since (there's complete network loss, and even the local authentication terminal is frozen). A reboot usually fixes the problem, but only temporarily. I cannot post a log since I have to trigger a forceful reboot. I've never had this problem before, and I have not pushed any hypervisor updates as of recent. I think it's safe to assume that my problem is caused by some kind of hardware failure or Unraid installation corruption.

Like I said, I'm running Unraid 6.1.9 on an ESXI Hypervisor, Unraid is booting from a 8GB Flashdrive, 16GB DDR3 RAM, 12TB pool with 7 drives, 240GB RAID 0 cache pool (2x128GB cache SSDs), AMD FX6300 6x3.5 no HT.

Since the last reboot (as I'm writing this up) I got a SMART warning regarding the relocated CT-count of my second drive. I am aware of the age of this drive and have a spare one to go, though I do not suspect this could be the reason of Unraid freezing. Could it?

I can confirm complete network loss: https://gyazo.com/3692b5babc2fb6316b2c7b6d2fae35df

Any idea as to why this is happening? Many thanks in advance!

Yeah... I'm starting to think it might be that failing drive... Every time the box comes back online after a freeze, the RSC value increases by 50-100 sectors... I'm going to swap it and report back. Could anyone explain why a failing drive is making Unraid hang?
