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.

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).

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"

Bye,
Oleg

Yes I know about problem with kmail 3.0x, but in my case this is kmail 3.1.2. Anyway nolargeio=1 has solved this problem for me. Thanks for the help!
