The limdaemon(1MSRM) program is the Solaris Resource Manager user-mode daemon. It is normally invoked at transition to run-level 2 or 3 as the last step in the Solaris Resource Manager init.d script. It shouldn't be confused with the srmgr system process (in the SYS class) that is initiated by the kernel. The following ps(1) listing shows both these processes:
# ps -efc | egrep 'limdaemon|srmgr' root 4 0 SYS 60 18:42:14 ? 0:05 srmgr root 92 1 SHR 19 18:42:32 ? 0:41 limdaemon
Receives notification messages and delivers them to the terminals of destination users
Receives login or log out notification messages, maintaining an exact record of all Solaris Resource Manager login sessions currently in progress
Periodically updates the connect-time usages for all users who have Solaris Resource Manager login sessions currently in progress (optional)
Detects users who have reached their connect-time limit, kills their processes, and logs them out (optional) after a grace interval
Logs all actions using syslog(3C) to syslogd(1M)
When notified of Solaris Resource Manager login sessions, limdaemon monitors the terminal connect-time of all users and checks it against their connect-time limits. When limits are nearly reached, users are sent notification messages. Once the expiration time is reached, a further grace period is allowed before all their processes are terminated and they are logged out.
The limdaemon program decays connect-time usages. Usage decay for the terminal device category must be performed, if connect-time limits are used. Refer to Using limdaemon for information on limdaemon command-line options.
