The above error happened just after pop3-login process was created.  
So if it doesn't happen every time, it means that you were globally  
running low on available file descriptors. NFS, indexes and such  
probably don't matter here. If it happens often you should find out  
where all the file descriptors are going.

Fixed now in CVS: http://dovecot.org/list/dovecot-cvs/2007-January/ 
007344.html

Should be pretty rare problem, and even then it doesn't really matter  
much since it crashes only after user has been disconnected.

This is bad.

These all seem to be related. What patching did I suggest? Do these  
still happen? If you could get a gdb backtrace from these, it'd be  
really helpful. See http://dovecot.org/bugreport.html
