1 Title: Fixed possible deadlock in shutdown/restart procedure
10 During the shutdown/restart procedure of the livestatus proxy
11 daemon a deadlock could occur. It seems this could rarely happen

20 Workaround: In such a situation it is safe to simply kill all those
21 processes using SIGKILL and start a clean liveproxyd processes after
