[PVE-User] Server freezes without log messages

[David Hackl]

Dear PVE people,

I'm using the newest proxmox version, installed on an debian minimal 
image. Everything works as expected. But sometimes the server seems to 
freeze without any reason for that.

I checked all important logfiles but there is nothing about the freeze. 
It doesn't happen the whole time. Seems like it's a random thing. The 
first freeze was about 1 1/2 month ago I think, the next after 12 hours. 
Then nothing for weeks. Again a freeze three weeks ago and now yesterday 
one.

Any idea how I can find out what the problem is?

Best Regards,
David
