       cyrus-master - cyrus-master Cyrus process

       cyrus-master [ -C alternate imapd.conf ] [ -M alternate cyrus.conf ] [ -l

       janitor period ] [ -d ] [ -D ] [ -x snmp agentx socket ]

       Cyrus-master is the process that controls all of the Cyrus processes.
       This process is responsible for creating all imapd, pop3d, lmtpd and
       sieved child processes. This process also initializes the Berkeley DB
       code and performs scheduled cleanup/maintenance.

       If this process dies, then no new sessions will be started.

       It kills itself and all child processes when it receives a SIGTERM.

       -C alternate imapd.conf
              Specifies an alternate imapd.conf for use by cyrus-master (note
              that this will not affect any sub-processes spawned by cyrus-
              master, you should specify those specifically in the respective
              entries in cyrus.conf).

       -M alternate cyrus.conf
              Specifies an alternate cyrus.conf for use by cyrus-master.

       -l listen queue backlog
              Increase the listen queue backlog. By default, the listen queue is
              set to 32.   On systems with a high connection rate, it may be
              desirable to increase this value. refer to listen(2) for details.

       -j janitor full-sweeps per second
              Sets the amount of times per second the janitor should sweep the
              entire child table.  Leave it at the default of 1 unless you have
              a really high fork rate (and you have not increased the child hash
              table size when you compiled Cyrus from its default of 10000

       -p pidfile
              Use pidfile as the pidfile.  If not specified, defaults to

       -P snmp agentx ping interval
              Sets the amount on time in seconds the subagent will try and
              reconnect to the cyrus-master agent (snmpd) if it ever becomes (or
              starts) disconnected.  Requires net-snmp 5.0 or higher.

       -d     Start in daemon mode (run in background and disconnect from
              controlling terminal).

       -D     Don't close stdin/stdout/stderr. Primiarly useful for debugging.

       -x snmp agentx socket
              Address the cyrus-master agent (most likely snmpd) listens on.
              Requires net-snmp 5.0 or higher.

       Upon execution, cyrus-master reads its configuration information out of
       the cyrus.conf(5) file.

       Cyrus-master rereads its configuration file when it receives a hangup
       signal, SIGHUP.  Services and events may be added, deleted or modified
       when the configuration file is reread.  Any active services removed from
       the configuration file will be allowed to run until completion.

       The environment variable CYRUS_VERBOSE can be set to log additional
       debugging information. Setting the value to 1 results in base level
       logging.  Setting it higher results in more log messages being generated.
