Executive shutdown



RTEMS version 4.6
Target PC386

I have written a device driver to use the rtc to generate timer interrupts
independent of the clock used to drive rtems. I have set  the additional
timer to produce interupts at 122micro second intervals, these are then
counted and when the required time interval has elapsed a POSIX signal is
sent to a thread.

If I set the signal to be sent every  2 miliseconds the system eventually
crashes with an executive shutdown. However, if set to 20ms it works fine.

Does any one have any ideas what may be causeing the problem, and how can I
get a trace of what cause the executive shutdown.

Thank You

Brian Stevens
