Description Lucia Mrenica 2019-05-04 08:05:40 UTC 
Process jfs_debugfs is using 100% of one cpu core, and kpmcore_externalcommand grows in size until it fills the entire memory (memory leak).


STEPS TO REPRODUCE
1. Create a partition with jfs

OBSERVED RESULT
When Partition manager performs the scan after finishing all jobs it gets stuck.

EXPECTED RESULT
The scann would pass and Partition manager would continue working as it does with any other Filesystem

SOFTWARE/OS VERSIONS
Partitionmanager Version: 4.0.0
KDE Plasma Version: 5.15.4
KDE Frameworks Version: 5.57
Qt Version: 5.13.0beta3
Comment 1 Andrius Štikonas 2019-05-10 20:30:39 UTC 
what is the version of jfsutils?

I have 1.1.15 and it seems to work fine.

What about if you run jfs_debugfs manually.

KDE Partition Manager basically runs

"jfs_debugfs /dev/sdb1"

and inputs "dm"

Maybe you can paste the output of that command?
Comment 2 Lucia Mrenica 2019-05-11 07:24:30 UTC 
sudo jfs_debugfs /dev/sdb1
jfs_debugfs version 1.1.15, 04-Mar-2011

On first glance, I can't see anything wrong with this. Program starts normally, operates normally (no slowdowns or anything) and exits normally.
