Re: [hobbit] Re: Status not available
Is it possible that the SIGUSR2 signal is not being sent properly?
What signal is sent to kill hobbitd from hobbitlaunch if it doesn't
recieve notice?
The HEARTBEAT keyword can only be used for one task, and is
specifically aimed at monitoring the hobbitd(8) task. This
task must send a SIGUSR2 signal to hobbitlaunch regularly;
if this signal fails to arrive for more than 15 seconds,
hobbitlaunch will kill the running task and start up a new
one. hobbitd(8) will send this signal every 5 seconds.
