I am running dovecot 1.1.10 and 1.1.11 on Solaris 10, mailboxes are in mbox format and served by Solaris 10 NFSv3, the dovecot cache is on local disk.
Some of my users always had above nfs error and their mailbox usually very big, over 100M, 400M, or even 800M.
Please don't put the entire error message in the subject.
Sorry about that.
Please post output of dovecot -n and some logs exhibiting the problem.
Here is some log entries.

The problem happens to users' with their inbox over 100M and it happens randomly.
