Well, the good news is this didn't end up being a dovecot or NetApp
issue. RHEL 6.2 has a kernel bug:
https://bugzilla.redhat.com/show_bug.cgi?id=770250
Solution is to upgrade to the latest kernel released on 5/15:
kernel-2.6.32-220.17.1.el6
We no longer get this error after the update. Thanks for taking a look!
