stage directory

[Andrew Morgan]

I just had a similar problem here today.  I saw that users could connect
to the imap port, but not imaps.  Also lmtpd process where hung (using
cpu) and unable to deliver mail.  In the syslogs I saw messages like:

master[18444]: can't fork process to run service imaps: Resource
temporarily unavailable

The fix was to increase the number of available file descriptors.  The
default on Debian Linux is 1024.  Also, the number of processes is limited
to 256 by default.  I increased it by putting the following two lines near
the top of my cyrus init script:

ulimit -n 209708
ulimit -u 2048
