running pthreads under SCHED_FIFO policy


Hi,

I've been 'playing around' converting the scheduling policy of one of my programs to run under SCHED_FIFO.

The program basically starts up a number of pthreads which all run concurrently until they are stopped externally.

I've had no problem changing the scheduling policy of the threads which are created by the main program but I keep getting SIGSTOP signals when I try and create any child threads from within one of the real-time threads.

The child threads I'm attempting to create are running under the SCHED_OTHER scheduling policy (basically they have the default attr settings).

Can anyone explain what's going on?

Am I attempting an impossible operation? Should the child threads have SCHED_FIFO attributes? Is there a confict of resources when creating a new thread while running with in real-time?

Thanks
