Funny thing is that I've checked that the daemon is not running and then done a 'scvadm clear inadyn' and get these failures. > Can you do ptree -c `pgrep inadyn` to see if the daemon is started by > svc.startd?

I'll check this, but AFAICT, the daemon is not running when I do a 'svcadm clear inadyn'. > >> Let's start with the failure I have: >> >> -bash-3.00$ svcs -xv inadyn >> svc:/network/ddns/client:inadyn (Dynamic DNS client) >> State: maintenance since Mon Nov 13 12:07:39 2006 >> Reason: Restarting too quickly. >> See: http://sun.com/msg/SMF-8000-L5 >> See: man -M /usr/local/man -s 8 inadyn >> See: /var/svc/log/network-ddns-client:inadyn.log >> Impact: This service is not running. >> >> and in the tail of the log, there is: >> >> -bash-3.00$ tail -20 /var/svc/log/network-ddns-client\:inadyn.log >> [ Nov 13 19:14:11 Executing start method >> ("/usr/local/lib/svc/method/inadyn-client start") ] >> 'inadyn' is already running >> [ Nov 13 19:14:12 Method "start" exited with status 0 ] >> [ Nov 13 19:14:12 Stopping because all processes in service exited. ] >> [ Nov 13 19:14:12 Executing stop method (:kill) ] >> [ Nov 13 19:14:13 Executing start method >> ("/usr/local/lib/svc/method/inadyn-client start") ] >> 'inadyn' is already running >> [ Nov 13 19:14:14 Method "start" exited with status 0 ] >> [ Nov 13 19:14:14 Stopping because service disabled. ] >> [ Nov 13 19:14:14 Executing stop method (:kill) ] >> >> The manifest is attached, but the start method is: >> >> <exec_method type='method' name='start' >> exec='/usr/local/lib/svc/method/inadyn-client %m' >> timeout_seconds='300'> >> <method_context> >> <method_credential user="root" group="root"/> >> </method_context> >> </exec_method> >> >> which uses the inadyn-client script (that I wrote), containing the >> following lines (code edited): >> >> #!/sbin/sh >> >> . /lib/svc/share/smf_include.sh >> >> NAME=inadyn >> DAEMON=/usr/local/bin/$NAME >> . >> . >> . >> case $1 in >> start) >> if [ ! -x $DAEMON ]; then >> echo "$DAEMON is not executable, not starting" >> exit $SMF_EXIT_ERR_CONFIG >> fi >> if [ ! -r $CONF ]; then >> echo "$CONF not readable, not starting" >> exit $SMF_EXIT_ERR_CONFIG >> fi >> if pgrep $NAME >/dev/null; then >> echo "'$NAME' is already running" >> else >> $DAEMON & >> sleep 1 >> fi >> ;; >> . >> . >> . >> esac >> >> exit $SMF_EXIT_OK >> >> When I call the 'inadyn-client' script directly, the daemon starts well >> and keeps going without a glitch, but when svc.startd tries to start it, >> it decides somehow that "all processes in the service exited".
