[Dovecot] fstat() errors on /srv/mail/<username>/dovecot.index.log

Dovecot version 2.1.7
Ubuntu 12.04.3 LTS
Kernel 3.2.0-35-generic x86_64

I'm not sure exactly when this started occurring, but sporatically users
report issues receiving email, having email saved to "Sent," etc. 
Looking in dovecot.log, I see the following errors:

These errors are not confined to a single user, and do not occur with
the same frequency.

I originally was running the Dovecot shipped with the default Ubuntu
repositories (don't remember which version, but it was 1.*) and used a
backport to upgrade to 2.1.7 to see if that fixed it.  It did not.

Any ideas why this is happening?

gawd knows what debian (thats all ubuntu is, same package maintainers 
99% of time) do to things, wouldnt be the first time they put out a 
package that was kaput from get go, so doveconf -n  output will likely 
be required
