Hi,
I have been having this problem for quite a while, in fact, but I just have
taken the time to diagnose it.
Kmail eats a lot of CPU on my machine, specifically when one account is
activated.
If I use the akonadi console, I see it doing

KMail Kernel ETM (0x104c840) 1986 OK FETCH completed
all the time, with tens of thousands of messages. The akonadi console cannot
keep up… I have to activate debug only for one second, then it scrolls for at
least 10 seconds. These messages never stop. And if I try to capture for a
minute or so, akonadiconsole gets out of RAM.
I guess there is something it doesn't like in an imap folder... It's been doing
this on this account for at least 2 years. I have tried Kmail2 again at each
KDE release, and switched back because of that. I know I should have given it a
look before...
I tried to let it run for 24 hours, hoping it would settle. But it doesn't and
always comes back to fetching all emails in these few folders (always the same
3 or 4 collectionids).
I have 3 other accounts with no problem. Can I provide some more information ?
A log , a debug trace, whatever may help you solve this problem ?
