NAME

searchmonitor - SWISH++ search daemon monitor  

SYNOPSIS

searchmonitor [ -c conf_file ] [ -s search_path ]  

DESCRIPTION

searchmonitor is a process monitor for search(1) when it is running as a daemon. If the process exits because of a condition that restarting might cure, it will automatically be restarted.

searchmonitor is typcially called from a system start script such as searchd(8) (for SysV-like systems) or rc.local (for BSD-like systems).  

Restartable Conditions

The following conditions will cause a restart:
*
A create, bind, or listen to a TCP or Unix domain socket fails.
*
A select or an accept on a socket fails.
*
Creating or detaching a thread fails.
*
Initializing a thread mutex or condition fails.
*
Any unaccounted-for exit status.

Restartable conditions are logged via syslogd(8) at the ERR level. There is a 5-second sleep before the process is restarted to prevent tight loops.  

Unrestartable Conditions

The following conditions will not cause a restart:
*
Error in configuration file.
*
Error in command-line.
*
Reading the index file fails.
*
Writing the PID file fails.
*
Deleting an old Unix domain socket file fails.
*
Changing directory to / fails.
*
The user or group the process is attempting to change its user and group ID to does not exist.
*
The process received a USR2 signal in response to a manual shutdown request.

With the exception of USR2, unrestartable conditions are logged via syslogd(8) at the ALERT level.
