See the doveconf output below.

I am using a single server, mbox, local disks (/home and /var is XFS on
HP SmartArray).

I tried dovecot 2.2.7, 2.2.10 and 2.2.12. All of them produce tha same
errors. ("Cached message size smaller than expected", sometimes followed
by "read... Invalid argument".)

2.1.1 seems to only produce "Cached message size smaller than expected"
without the read errors.
