[monit] monit starts a process twice

[Nick Upson]

Here is an extract from the log, with additonal comments as I *may*
have an idea of the problem

Mon Feb  4 08:28:07 MST 2008 restart bs1
# this is me issueing the command for the restart

[MST Feb  4 08:28:07] info     : restart service 'bs1' on user request
[MST Feb  4 08:28:07] info     : monit daemon at 10762 awakened
[MST Feb  4 08:28:07] info     : Awakened by User defined signal 1
[MST Feb  4 08:28:07] info     : 'bs1' trying to restart

[MST Feb  4 08:28:07] info     : 'bs1' stop: /opt/unb/bin/bs.sh
# everything as expected so far

[MST Feb  4 08:28:08] debug    : 'bs1' Error testing process id
[10793] -- No such process
[MST Feb  4 08:28:08] debug    : 'bs1' Error testing process id
[10793] -- No such process
[MST Feb  4 08:28:08] debug    : 'bs1' Error testing process id
[10793] -- No such process
# now why is monit complaining about the process it says it has
stopped monitoring


[MST Feb  4 08:28:08] info     : 'bs1' start: /opt/unb/bin/bs.sh
# this does work and did start it running as shown by ps output


[MST Feb  4 08:28:08] debug    : 'bs1' Error testing process id
[10793] -- No such process
# and by this point the pid in the pid file should have the new pid in it

[MST Feb  4 08:28:08] debug    : Monitoring enabled -- service bs1

# and from here on monit is happy about the second copy but the first
one is still there as well
