How often do they happen? If it really is related to time, the only thing I can think of is that daylight saving time changed, which increased/decreased some timestamp string and broke some length calculation..
We've upgraded to the latest Dovecot 1.2.11 and are using Dovecot 'deliver' exclusively. Tried setting fsync_disable=no, but the problem persists.
You could try mbox_lazy_writes=no and mbox_dirty_syncs=no, although disabling lazy writing makes the performance worse. Let me know if those fix it..
