Summary:                    missing exim pidfile
Description: 
This is with:

/var/opt/csw/pkgutil/packages/exim-4.76,REV=2012.05.07-SunOS5.9-i386-CSW.pkg

The start clause in /var/opt/csw/svc/method/svc-cswexim reads (excerpts):


DAEMON=/opt/csw/sbin/exim
PIDFILE=/var/run/exim.pid

test -z "$EXIM_PARAMS" && EXIM_PARAMS="-bd -q30m"

case "$1" in
  start)
    echo "Starting MTA: \c"
    $DAEMON $EXIM_PARAMS
    echo "exim."
    ;;


This borks svcadm for disable and restart, as found in
/var/svc/log/network-cswexim:default.log:

[ Aug  2 17:10:59 Stopping because service disabled. ]
[ Aug  2 17:10:59 Executing stop method
("/var/opt/csw/svc/method/svc-cswexim stop"). ]
Stopping MTA: cat: cannot open /var/run/exim.pid: No such file or
directory
Usage: kill [-l] [-n signum] [-s signame] job ...
   Or: kill [ options ] -l [arg ...]


Because stop etc. need to read the pidfile:

  stop)
    echo "Stopping MTA: \c"
    kill `cat "$PIDFILE"`
    echo "exim."
      ;;


To fix this, please have exim write a pid file.

In /var/opt/csw/svc/method/svc-cswexim:

test -z "$EXIM_PARAMS" && EXIM_PARAMS="-bd -oP ${PIDFILE} -q30m"

In /etc/opt/csw/exim/exim-env.sh:

EXIM_PARAMS="-bd -oP /var/run/exim.pid -q30m"

My apologies for the delay.

I installed this:

http://buildfarm.opencsw.org/experimental/exim/exim-4.80,REV=2012.08.04-SunOS5.10-i386-CSW.pkg.gz

I found that it correctly creates a pid file on exim installation and
"svcadm enable network/cswexim".

One caveat is that the experimental package doesn't remove
/var/run/exim.pid when I run "svcadm disable network/cswexim". This can be
a problem with software like monit, where it may check for a running
process using the pid from the pidfile, and run the start script if the
process doesn't exist.

(Obviously Solaris has SMF, but you never know what people may decide to
install.)
