8/5 22:42:37 Our parent process (pid 16496) went away; shutting down
8/5 22:42:37 Got SIGTERM. Performing graceful shutdown.
I don't know who is this "parent process" : there was only thre daemons : collector (16497), negotiator (16498) and shedd (16499)
Has someone an explication ? Is there an option to set, so the daemons never exited ?
