error -- unknown resource ID: [4]

[Former user]

Running monit 5.23.0 on CentOS 6.6, I have the following check for nginx:

check process nginx with pidfile /var/run/nginx.pid
  group webserver
  start program = "/sbin/service nginx start"
  stop program = "/sbin/service nginx stop"
  if cpu > 60% for 2 cycles then alert
  if cpu > 80% for 5 cycles then restart
  if children > 250 then restart
  if loadavg (1min) > 90 for 15 cycles then alert

The loadavg (1min) line appears to cause the following error to be repeated over and over in the monit log:

[EDT Sep 12 12:05:09] error    : 'nginx' error -- unknown resource ID: [4]

I've tried different times (e.g. 5min) and the resource ID changes in the error message (as expected). I don't think this is actually an error, but it's appearing in the log every cycle.

The "loadavg" statement can be used in "check system" context only (load average is system property, not process'). Please remove the following statement and reload monit:

if loadavg (1min) > 90 for 15 cycles then alert

Ah, that's what I assumed but it used to work and there were examples in the manual. I've opened https://bitbucket.org/tildeslash/monit/pull-requests/53 to address.
