Update: There was a second hang at around 09. The reason for the hangs has been found and fixed.
There was a short hang on the /nird/home ($HOME) file system on Fram from 08:00 to 08:55 today. The file system is back to normal now. We are investigating the reason for it.
Jobs running in $SCRATCH, $USERWORK or in a project directory have most likely not been affected, but it is probably a good idea to check the status of your jobs.
