Hello Timo, Hello list,
we are running 4 hosts with director+dovecot instances and storage on shared NFSv4.
Last week we upgraded to 2.1.13 and since then we encountered the same issues as Morten Stevens. We got a lot of error messages with corrupt index cache and FETCH errors: So we had to roll back to dovecot 2.1.10. Now the errors are gone.

This critical bug must have been introduced with the latest hg patches somewhere between 2.1.10 and 2.1.13. Please find and revert the problematic changes, since they break the 2.1.x stable release for us.
I'll send you m.3070 obfuscated and gzipped in a separate mail.
