NAME

       cyrmaster - master Cyrus process

SYNOPSIS

       cyrmaster  [ -C alternate imapd.conf ] [ -M alternate cyrus.conf ] [ -l
       listen queue ] [ -p pidfile ] [ -P snmp agentx ping  interval  ]  [  -j
       janitor period ] [ -d ] [ -D ] [ -x snmp agentx socket ]

DESCRIPTION

       cyrmaster 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.

OPTIONS

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

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

       -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 entries).

       -p pidfile
              Use pidfile as the  pidfile.   If  not  specified,  defaults  to
              /var/run/cyrmaster.pid

       -P snmp agentx ping interval
              Sets  the  amount  on  time in seconds the subagent will try and
              reconnect to the 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  master  agent  (most  likely  snmpd)  listens  on.
              Requires net-snmp 5.0 or higher.

CONFIGURATION

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

       cyrmaster 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.

NOTES

       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.

BUGS

       Services do not always go away silently when removed through a  SIGHUP.
       If  there are workers of the removed service still running, messages to
       syslog about broken pipes and accept() failures are to be expected.

       The in-memory list of services is not cleaned up ever, so  a  cyrmaster
       daemon that has been sent an extremely high amount of SIGHUP signals to
       add/remove/modify   services   will   lose   performance    eventually.
       Restarting cyrmaster fixes this.
