Hi Theodore, Thanks for your reply.
As far as I know the system is not swapping, at least not a lot, but as indicated, very hard to figure out what is going on without being able to use a terminal screen. I also set the swap space to another disk than the disk that seems to be causing the issue. And yes, I know it has (probably) nothing to do with e2fsprogs, but I had to choose something when reporting the error (using command line utility). And to me no matter what it is, it is still kind of a bug. I think an OS virtually freezing like this is not a stable OS. I am trying to change the disk scheduler now to see if that changes anything. Please note I started using ionice and nice for the suspect processes. That doesn't seem to make any difference. Looking forward to more info about how I can figure out what is going on, Kind regards, Guus On Monday, 16 April, 2018 10:58 PM, Theodore Ts'o wrote: > Your system sounds like its thrashing due your processes wanting to you > more memory than is available in your system.
