about send in rtems_timer_service_routine

[Daron Chabot]

Not having checked send(2) for blocking behavior, this is just a guess:

The function, rtems_timer_service_routine( ), is called from an  
interrupt context. Code called from an interrupt context *cannot*  
perform operations that may block waiting for resources (i.e. send(2)).

You could use an rtems_timer_server instead: this server runs in a  
thread context which has no restrictions on the methods invoked from it.
