Subject: high system usage with kmail in 2.5.7X
Date: Thu, 3 Jul 2003 16:37:46 +0400 [thread overview]
Message-ID: <200307031637.46227.rathamahata@php4.ru> (raw)
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.
