Hi, I don't have a dovecot log specified in the config, so I believe  
everything goes to syslog which I think all ends up in either maillog  
or messages. I don't see anything in there with "Warning".

In this case, no I'm not using NFS. The server on which I'm seeing  
this problem has the maildir data on a local ZFS file system. I have a  
sort of poor mans cluster where I can run all the services on one of  
two servers which may or may not use NFS, but as mentioned in this  
instance there is no NFS to worry about.

thanks Andy.
