I would like to use the --delaytime option when running the ocsinventory-agent as a daemon, but the --delaytime option does not seems to support specifying the delay in seconds and if I try to specify it with --delaytime 600 (and the server is not available on the first run), then the process goes into an infinite loop with 100% CPU usage and the message "Going to sleep for 0 second(s)" printed in the log.
The problem comes from the fact that the getopt definition of the --delaytime option does not specify that it takes an argument (number of seconds for the delay).
So, the option is considered a boolean option and affected a value of 1 when present.
Later, when the value is used to select a random delay (with rand($delaytime = 1)) it always returns 0 causing the process to retry immediately without delay.
The problem only occurs when trying to specify the delaytime from the command-line. Specifying the delaytime in the configuration file does not shows the problem.
Inventory log file ( optional )
Try to specify a --delaytime 600 when running the agent:
# /usr/bin/ocsinventory-agent -d --delaytime 600
The agent goes into an infinite loop with 0 sec. delay:
# tail -F /var/log/ocsinventory-agent.log
