Description Silver Salonen 2012-06-27 08:44:39 UTC

I have eGroupware DAV resource in Akonadi. Its akonadi_davgroupware_resource process takes an increasing amount of memory over the time, even though I do nothing with it - KOrganizer just sits on the system tray.

Current memory information fro System Monitor:

Library Usage
The memory usage of a process is found by adding up the memory usage of each of its libraries, plus the process's own heap, stack and any other mappings.

Reproducible: Always

Steps to Reproduce:
1. Add eGroupware resource into Akonadi
2. Start KOrganizer
3. Wait and watch the memory usage
Actual Results:  
Memory usage increases over the time

Expected Results:  
Memory usage should stay approximately the same

I am seeing something similar, but I'm not sure that it is a leak.
I have four Google calendars that I sync with that are DAV groupware resources.  During sync, the akonadi_davgroupware_resource process slowly eats up to ~230 MB memory.  On successive syncs, the memory does not increase.  I don't know if ~230 MB is normal for this kind of activity.
How do you get that detailed memory usage per library?

Comment 2 Denis Kurz 2016-09-24 20:37:02 UTC

This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.

Comment 3 Denis Kurz 2017-01-07 21:48:41 UTC

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
