Error after setting Realtime Scheduling=on

Hi,

I got the following error from gnuradio companion:

GThread-ERROR **: file
/build/buildd/glib2.0-2.30.0/./gthread/gthread-posix.c: line 348
(g_thread_create_posix_impl): error ‘Invalid argument’ during
‘pthread_attr_setschedparam (&attr, &sched)’

Done

Google did not reveal too much to me either.

With kind regards

Mario
