Do you have issues with really slow start times for delayed jobs? How often is your monit config set to check on it?

Hi! I used this solution.

check process delayed_job_0
  with pidfile /u/apps/ticketing_production/shared/pids/delayed_job.0.pid
  start program = "/bin/su - avayo -c '/u/apps/ticketing_production/current/script/delayed_job start -i 0'"
  stop program = "/bin/su - avayo -c '/u/apps/ticketing_production/current/script/delayed_job stop -i 0'"

check process delayed_job_1
  with pidfile /u/apps/ticketing_production/shared/pids/delayed_job.1.pid
  start program = "/bin/su - avayo -c '/u/apps/ticketing_production/current/script/delayed_job start -i 1'"
  stop program = "/bin/su - avayo -c '/u/apps/ticketing_production/current/script/delayed_job stop -i 1'"
