Re: monit suddenly won't start

[Martin Pala]

Thanks for the files :) The problem is fixed in the CVS now.

It was caused by the special case where two joined include files formed 
one configuration rule. It was caused for example in this case:

unicorn:/etc# cat monit.d/infobot monit.d/dovecot
--8<--
check process infobot with pidfile /var/run/infobot.pid
        start program "/etc/init.d/flooterbuck start"
        stop program "/etc/init.d/flooterbuck stop"
        if 5 restarts within 5 cycles then timeout
        depends on ircd
check process dovecot with pidfile /var/run/dovecot/master.pid
   group dovecot-imap
   start program = "/etc/init.d/dovecot start"
   stop  program = "/etc/init.d/dovecot stop"
   if failed host foo.bar port 143 type TCP protocol IMAP
        then restart
   if 5 restarts within 5 cycles then timeout
   depends on dovecot_bin

...
--8<--

As you can see, although the infobot and dovecot configurations are 
standalone, the joined text is not valid since the parser kept the 
"depends on ..." state of the 'infobot' even when parsing the 'dovecot'. 
This created the following rule in the parser stack:

  depends on ircd check process ...

which is not correct.


Monit now presents the particular include files as standalone statements 
so the above example is parsed correctly now.

Thanks :)
