Call traces found on your server

Featured Replies

Hi,

 

My server has been crashing a bit recently - maybe once a week. There seem to be a lot of these errors in the syslog:

Jul  6 14:48:27 nas kernel: CPU: 0 PID: 8477 Comm: CPU 0/KVM Tainted: G        W       4.9.30-unRAID #1

 

And the call trace looks like below. One of my VMs?
