Hello,
I have been seeing an issue with Dovecot 2.2.5 (which is the current version packaged by cPanel). This is happening with any action that tries to access the mailbox index via IMAP. This log and debug information comes from a force-resync attempt, however, the same errors are logged when the user tries to open the mailbox or move a message to it. (User, domain, and IPs in log have been changed for privacy reasons).
System is a CentOS 5.10 (x64) VPS under Virtuozzo 4.0, and is not OOMing or hitting any container limits. User is connecting from multiple devices on the same IP, most of which are Apple Mail & iOS. Other users with only Apple Mail & iOS devices are also experiencing the same errors.
