Description kramski 2023-07-02 10:07:06 UTC

SUMMARY
akonadi_indexing_agent is consuming all available memory in only a few minutes until system gets Out-Of-Memory.

STEPS TO REPRODUCE
"akonadictl start" (if not already running)

OBSERVED RESULT
Watch akonadi_indexing_agent consume more and more gigabytes of memory in only a few minutes (I have 16 GB installed) until your desktop comes to a crawl.
Wait for the Linux OOM manager to kick in or "killall akonadi_indexing_agent" if you are still able to enter commands.

EXPECTED RESULT
On a similar system akonadi_indexing_agent statically consumes about 650 MB RAM.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.27.6
KDE Frameworks Version: 5.107.0
Qt Version: 5.15.10

ADDITIONAL INFORMATION
Also seen on a similar system (Laptop) with a different user account.

Current workaround is "killall akonadi_indexing_agent" multiple times until the agent gives up to restart.

Already tried "aconadictl fsck" and  "aconadictl vacuum" to no avail.

I "solved" this by renaming ~/.local/share/akonadi/search_db to ~/.local/share/akonadi/search_db.bad as suggested in https://linux.debian.user.german.narkive.com/BXFXGrPF/kmail-zeigt-keine-mails-mehr-an#post11.
