high system usage with kmail in 2.5.7X

high system usage with kmail in 2.5.7X

Post by Sergey S. Kostylio » Fri, 04 Jul 2003 14:40:16



Hello all,

I experienced an abnormally high system usage whith kmail
(KDE mail client). This is usually happened when I click on a
huge mail folder. Then kmail just stops responding for a dozens of seconds.

Seems like problem started around 2.5.70 (2.5.69 doesn't compile on my box,
2.5.68 works fine for me).

I understood that this problem can be related to kmail itself, but a high
system usage during this seems strange for me. Any hints are welcome.

Kernel version is 2.5.74. Filesystem is reiserfs.

This is a kmail 3.0x problem (with large recommended i/o sizes), it is reported that upgrading to kmail 3.1+ will help.
Alternatively you can mount your reiserfs volumes with "-o nolargeio=1"
