Description Robin Rosenberg 2004-11-02 20:50:10 UTC 
Version:           1.7.1 (using KDE 3.2.3, Mandrake Linux Cooker i586 - Cooker)
Compiler:          gcc version 3.4.1 (Mandrakelinux 10.1 3.4.1-4mdk)
OS:                Linux (i686) release 2.6.8.1-12mdk

Every now and then (~5 minutes) kmail scans all my local folders. Since my local folders contain ~20000 messages in total this slows down the system directly through disk accesses and indirectly through flushing file system caches.

It seems all folders are read through (strace'd kontact), even very old archives that are not used by any filters.

It also used huge amounts of CPU, not just disk.
Comment 2 Tom Albers 2004-11-03 17:43:44 UTC 
Do you use the expire function?
Comment 3 Robin Rosenberg 2004-11-04 14:40:04 UTC 
No, I don't use the expire function
Comment 4 David Faure 2004-11-04 15:00:53 UTC 
Any search folders?
Comment 5 Robin Rosenberg 2004-11-04 15:48:03 UTC 
Yes, one. (implicitly created). I'll remove it and see.
Comment 6 Robin Rosenberg 2004-11-10 12:33:16 UTC 
It was the search folder.

Is it necessary to create the search folder? I'm not using it directly. I'm invoking the search funtion which gives me a dialog. I don't want a permanent search folder to be established for that.
Comment 7 Carsten Burghardt 2004-11-11 17:24:37 UTC 
Yes we need to create a search folder. But you can delete it afterwards of course. And if you don't rename it it will be deleted when you close kmail.
Comment 8 Robin Rosenberg 2004-11-11 17:40:05 UTC 
I never renamed it and it wasn't deleted.
Comment 9 Don Sanders 2004-12-22 06:40:47 UTC 
This change probably hasn't made it downstream to you yet.

Be conservative and remove the 'Last Search' folder at start up.

Don.

Hm, I have kdepim 3.5.9 and "last search" folder isn't deleted at startup.
