Server keeps locking up. Unable to capture syslog. Need troubleshooting advice.

[knalbone]

A couple of weeks ago I posted a topic stating that I thought I had a bad cache drive. link

I ended up coming to the conclusion that it was just a bad docker image and recreated my image and containers.

 

Fast forward 1 week and my server was completely locked up. I could not even login locally to the console and could not capture logs. The image shows the text on screen before I rebooted on 4/21

 

Within the past few days, I have had more lockups of my server. No web access, ssh, ping, or console access. Even pressing the power button on my server to initiate a powerdown will not work. Instead the process hangs as pictured below.

 

 

I have been able to "raise a skinny elephant" after each lockup to get the closest thing as possible to a clean shutdown, but its not enough to prevent a parity sync upon reboot.

 

Here are the timestamps of each time my server has stopped responding over the last few weeks:

21 Apr 2018 17:58:52

28 Apr 2018 23:26:53

29 Apr 2018 08:10:50

02 May 2018 05:48:53

02 May 2018 05:48:53

 

I have attached current diagnostics, but I know they likely won't containing much helpful info since I rebooted once again a couple of hours ago.

 

I suspect one of my cache drives is to blame, but I'm unsure how to troubleshoot or verify this. I have disabled the cache drive on all my shares for the time being. Docker containers are stopped while parity sync is running. 

 

Is there any kind of diagnostics I can run on my cache drives to figure out if one of them is causing my issues? Or should I try to troubleshoot something else.

Install the  Fix Common Problems   plugin and turn on the 'troubleshooting mode'.   That will write log files to the   logs   folder/directory on your flash drive.  There may be some clue as to what is happening in one of them.  

 

You also need to provide a list of the plugins and dockers that you are running.

Thanks. Fix common problems has been installed and troubleshooting mode is enabled.
