I'm looking for some help with an nfs error that is filling our logs. I get a constant stream of these messages:

Jul 8 10:47:08 servername dovecot: [ID 107833 mail.error] IMAP(username): nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy

What OS are your dovecot and NFS servers running? Is /var/mail (or whatever it may be symlinked to) an NFS mountpoint?

We're on Solaris 10x86 mounting /var/mail from another Solaris 10 hosts via NFS4.

Yes, /var/mail is an NFS. These are the mount options:

mayor.ics.uci.edu:/mail_tank_001/spools - /var/mail nfs -
yes rw,nosuid,hard,intr,bg,noac

Are you using Dovecot version 1.1.1? If you are using an earlier version (i.e. a 1.1 release candidate), there was an update that was made that eliminited these errors in certain circumstances. Specifically under Solaris I might add.

If you are using 1.1.1, I'll have to defer to others to solve the problem. I just remember running into those errors and having them disappear once I upgraded to a final release version.

Thanks Dean.

We are using Dovecot version 1.1.1. I was hopeful after seeing the earlier fixes for Solaris too. But now I wonder if there isn't just one more similar fix that needs to go in.
