Version: 1.11.4 (using 4.2.4 (KDE 4.2.4), Debian packages) Compiler: cc OS: Linux (x86_64) release 2.6.28-10 Sometimes KMail eats up a lot of RAM and the GUI is unresponsive during this time. I cannot 100% reproduce this ;-( AFAICT is happens sometimes when moving mails from inbox to another folder. Sometimes it also happens when kmail was killed and I restart it. My guess is that it reads all dimap mails into RAM. As I have ~7GB of mails in there and ~7.5GB RAM & SWAP this fits more or less, but the whole machine goes pretty slow. Thanks for writing KMail, I love it!
