I’m not really sure what causes the problem.
I think it first appeared after the latest upgrade on 1.7.3.
Sometimes (it just happens occasionally every 2 or 3 days) my Azure VM shows me huge disk writing. The VM is almost inaccessible even through putty. The websites just show 503.
I googled that a bit and installed fatrace to track what’s happening.
So this is a small excerpt from what I get from fatrace

This continues really long. But sometimes it resolves after a while and the VM continues as nothing ever happended.
When I see it happen, I usually restart the VM and the problem is solved for the next days.
So what is the problem? And how to fix it?
Any help and hints are appreciated
Thanks Alex
