[[6.12] Unraid webui stop responding then Nginx crash]

For what it’s worth I’ve just found this thread because I believe I’m having this issue running 6.12.6.

 

syslogs shows nginx crash and the whole server becomes unresponsive (even to pings) and I have to power off with the power button. 
 

it seems to happen when the server is idle for a couple of hours. 

[(6.12.3) Writes to ZFS pools constantally]

I have this exact same problem, I will get continous small bursts of writes of around 400Kb/s.

 

I have no dockers/VMs etc running, only an array, 2 cache drives and a few plugins.

 

I disabled the cache dirs plugin and zfs master refresh to see if it was those and I still got the continuous small bursts.

 

Only thing that iotop shows is that kworker is triggering when the writes happen.

 

Any ideas?
