Windows 7 VM, crashes and write "Call traces" in log

Recommended Posts

Posted (edited)

My Windows 7 VM is working for a couple of days and I'm pretty sure it's producing "trace calls" that I get warning of in the log file. And eventually it craches, it can also be a combo of dockers and vm that is making the "Call traces"

 

Here is my template xml:

I have no clue what so ever, the only thing I have changed to see if it helps is to install "tips and tweaks" and set:

vm.dirty_background_ratio = 2 %

vm.dirty_ratio = 3 %

 

But it doesn't help, eventually the log will get 100% full and unraid gets unresponsive and needs a reboot.

I'm testing a Windows 10 VM but I still get Call Traces, here is a sample for that:

I would really appreciate some help with this, I can't have a server I need to restart every week. :(
