The command that I use (on CenTOS 6.9) is:
#service centovacast status
This shows the current state of all of the sub-processes:
cc-control: running (pid 2236)
cc-appserver: running (pid 2263)
cc-comet: running (pid 2245)
cc-web: running (pid 5336)
cc-ftpd: running (pid 2268)
cc-imaged: running (pid 2276)
What do you get when you run the above command ?
We have written a PHP program that we run with a CRON job every 5 minutes to check the status of all of the sub-procrsses. If any of them are stopped, it issues a command:
#service centovacast restart
