Okay, I have one case of KMail getting stucks displaying mail and it seems to 
me that Akonadi IMAP resource is blocked out then:

Bug 343114 - gets stuck on one request that times out, kmail and 
akonadiconsole do not display any mail payloads anymore, stuck waiting 

I will archive the logs now. Please tell me what to look for. I won´t upload 
the whole 130 MiB of cleartext with folder names and complete mails in it due 
to privacy concerns.

Ciao,
