FYI, sorted out this issue by taking out a specific email manually. Not sure if it helps, but the email had these attributes:

Removing the email fixed the issue.

Could you try if the problem re-appears if you put that message into a new mailbox? If so, you could ask Timo to make it available to him, in order to investage the problem.

Couple of things.

1. Look at mail_process_size in dovecot.conf and make sure it's not insanely low like 128MB or something. If you're accessing mailboxen with 8000 messages, I'd set it to at least 512MB. The first error message you received tells you to look into this setting:

"Apr 21 19:15:17 dovecot: Error: child 25918 (imap) returned error 83 (Out of memory - see mail_process_size setting)"

2. If you are using 1.2.10 or below and mbox storage, you need to upgrade to 1.2.11 which fixes some mbox related problems that might be a factor in this problem of yours.
