Hi!

On CentOS-7:

$ cat /etc/CentOS-release CentOS Linux release 7.8.2003 (Core)

Was running du to examine the sizes of my backups and found du hung, running “ps -eLf /mnt/backup/backups” shows this:

# ps -eLf | grep du root 1185 1 1185 0 1 May01 ? 00:00:00 /usr/bin/abrt-watch-log -F Backtrace /var/log/Xorg.0.log — /usr/bin/abrt-dump-xorg -xD

root 11090 1 11090 11 1 15:08 pts/1 00:01:10 du -s /mnt/backup/backups

even after killing the du.

there were two DUs shown, I killed the parent (presumably the one I
started) but the one that remains seems to be un-killable.

This is what the output looked like before I killed du:

# ps -eLf | grep du root 1185 1 1185 0 1 May01 ? 00:00:00 /usr/bin/abrt-watch-log -F Backtrace /var/log/Xorg.0.log — /usr/bin/abrt-dump-xorg -xD

Oh, and I never did get the du out put I expected.

Anyone got a clue?

Thanks in advance!
