Bug ID: 431323
Summary: Was the swap file filled?
Product: krusader
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: krusader-bugs-n...@kde.org
Reporter: ptrenho...@gmail.com
CC: krusader-bugs-n...@kde.org
Target Milestone: ---
Application: krusader (2.7.2 "Peace of Mind")
Qt Version: 5.15.2
Frameworks Version: 5.75.0
Operating System: Linux 5.9.16-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (Thirty Three)
-- Information about the crash:
- What I was doing when the application crashed:
I was attempting to update my /Backups partition from my /Common partition;
$ df -h /Common /Backups
Filesystem Size Used Avail Use% Mounted on
/dev/sda7 723G 120G 604G 17% /Common
/dev/sda6 783G 523G 221G 71% /Backups
After running for about a week (On a fairly slow "AcePC," with an "atom"
processor.) I turned on the screen, and found the crash report. I suspect that
the data base being created (in core?) ran out of space. (I do have a fairly
large swap file:
$ swapon --show
NAME TYPE SIZE USED PRIO
/dev/sda4 partition 23.6G 107.1M -2
/dev/zram0 partition 1.8G 1.8G 100
but it looks like (see above) the in-ram swap was filled, and the backup swap
file was filling.) (Which may explain why the process ran for almost a week
before crashing.)
When I looked at the "syncronize" display during the week, I noticed that the
system was spending a lot of time getting details about directories that exist
on only one side. At lot of tme and effort could be avoided if that condition
was noted for latter processing when the user was selecting which items to
move. (I.e., if a whole directory tree is to be moved, why bother to look at
the elements of that tree? Only if the user wants to look at the tree elements
(by clicking on the tree root) would there be any need to list the tree
contents.)
