There are no long lived links in our 'stage.' subdirs.

% !!
ls -l /cyr[1-9]/stage./*
No match
%


We do re-use pop3 and imap server processes, though.
(-U 10 parameter on pop3d and imapd entries in /etc/cyrus.conf)

We also observe writes to the 'stage.' subdirs by imapd processes
but this is to be expected, isn't it ?
It's the pop3 processes behaviour which is puzzling me.
