Solution Type Technical Instruction Sure Solution 1017931.1 : Sun Fire[TM] 15K: Setting up SMS 1.2 "mld" service to receive domains syslog messages
PreviouslyPublishedAs 229192 Description Correctly setting up the System Management Software (SMS) 1.2 "mld" (message logging daemon) configuration to correlate to the domain OS "syslogd" configuration could help to alleviate a known SMS 1.2 "mld" memory leak condition. Steps to Follow The SMS "mld" service provides logging services to all SMS daemons and processes. "mld" is the first SMS daemon started by "ssd (1M)" in order to capture the output of all other SMS daemons and processes during their startup phases. Platform log messages are stored in: /var/opt/SUNWSMS/adm/platform/messages And domain log messages are stored in : /var/opt/SUNWSMS/adm/domain_id/messages The "mld" process on the system controller also receives syslog messages from the domains. Depending on the configuration of the "mld" process (via the mld.cf file) the messages are either logged or simply ignored. To alleviate an inherent issue with the SMS 1.2 "mld" service, where it could potentially run into a memory leak condition when processing incoming (from the domains' syslog) messages. We recommend correlating the SMS 1.2 "mld" configuration alignment with the domain OS "syslogd" configuration. Here is an example to correlate the "mld" service remote message reception configuration file contents against each specific domains syslog configuration. To align domain A's syslog configuration against "mld" remote messages reception setting for domain A as follows. On the System Controller (/etc/opt/SUNWSMS/config/mld.cf): *.err;kern.debug;daemon.notice;mail.crit /var/opt/SUNWSMS/adm/A/syslog In addition, the System Controller also uses the information housed in "/etc/opt/SUNWSMS/config/MAN.cf" file to document domain-to-SC, the SC-to-domain, and the SC-to-SC management network. For example, the MAN.cf documents the following IP address assignment for the SC-to-domain A I1 network connection : I1 SC-I1 v4u-15ka-sc-i1 192.168.103.1 Next, the "/etc/syslog.conf" on each domain resident in the Sun Fire[TM] 15K platform should be 'aligned' to the above mld.cf & MAN.cf configuration information. For example, based on the above SMS mld.cf and MAN.cf configuration, the domain A's /etc/syslog.conf should be as follows: *.err;kern.debug;daemon.notice;mail.crit @192.168.103.1 And the "syslogd" on the domains should be restarted (if any modifications were necessary on the domain OS's /etc/syslog.conf).
