Guru mediation now registers SIGUSR1 and SIGUSR2 by default for backward compatibility. SIGUSR1 will no longer be registered in a future release, so please use SIGUSR2 to generate reports.
Option "verbose" from group "DEFAULT" is deprecated for removal. Its value may be silently ignored in the future.
