Description Martin Steigerwald 2014-03-26 21:03:47 UTC

On testing performance issues with Akonadi I ran into this error message after I disabled Nepomuk mail indexing and downloaded / filtered new mail for a huge POP3 account with kernel-ml folder of about 220000 unread mails[1] I got this error and it seemed that the Akonadi maildir resource crashed. 

I got this once before already.

[1] See:
- [Kde-pim] Akonadi MySQL backend: tuning for larger accounts or switching to MariaDB with a different storage engine?
http://lists.kde.org/?l=kde-pim&m=139583561813493&w=2
- [kmail2] [Bug 331848] displaying, moving, deleting mails takes 10-20 seconds  when Akonadi synchronizes in background

Reproducible: Sometimes

Steps to Reproduce:
I don´t know yet.
Actual Results:  
Akonadi maildir agent hogging a Sandybridge core 100% for minutes. KMail didn´t respond anymore to any requests to display mails, change folders and so on.

And I got this:

Comment 1 Martin Steigerwald 2014-03-26 21:12:22 UTC

Probably could be related to Akonadi still trying to feed stuff into Nepomuk? How long does it take till Akonadi respect that I disabled mail indexing. Will observe this further and close if it doesn´t happen again.

Comment 2 Martin Steigerwald 2015-03-12 12:33:20 UTC

I did not see this anymore since quite some time, currently using Akonadi 1.13 current master, kdepimlibs and kdepim-runtime from 24th of February and KMail 4.14.2. Also its still Nepomuk related and Nepomuk is gone. Thus closing.
