Version: Version 1.11.4 Using KDE 4.2.4 (KDE 4.2.4) (using KDE 4.2.3) Compiler: gcc (Gentoo 4.3.2-r3 p1.6, pie-10.1.5) 4.3.2 OS: Linux Installed from: Gentoo Packages In various occasions, kmail freezes while fetching folders/messages from IMAP mailbox. This is kmail released with 4.2.4 (using kdelibs/kdepim from 4.2.4) top: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13442 maciek 20 0 2666m 1.2g 26m R 100 59.6 0:31.14 kmail Normal resource usage for kmail is at least 6 times lower. Application doesn't seem to crash however. Compiled with -O0 -ggdb (I may try with typical -O2 later)
I cannot experience it anymore (as of KDE 4.3.0 and above), so assuming it's fixed, I'm closing as resolved and will reopen if needed.
I didn't do any update or anything. This bug hit me out of the blue after restarting the machine (like I do every day (green IT :)). IMHO it has to do with kmail's notorious weaknesses in the I/O area. If I start off with the splash (local folder) kmail has normal behavior. As soon as I want to open inbox or sent-mail or some other mailbox, kmail starts using 95-100% cpu and becomes extremely slow without crashing. Even erasing the index-files did not have any effect. It has already destroyed my flags anyway (for the n-th time) While the rest of kontact is really great, kmail still lacks hugely lacks stability and reliability.
