Quantum Server Randomly Shut Down in Grizzly

Asked by Kevin-Yang

recently we upgraded to Grizzly for Quantum and noticed that the Quantum service randomly disappeared sometimes, which is running as a backend service by using command "quantum-server --conf_dir ... --conf_file... &". We did not have this issue for folsom version.
