Description (last modified by Gedare Bloom)
EPICS developers report:
I notice that the only internal usage of _CORE_message_queue_Send() in RTEMS is in rtems_message_queue_send(), where it never blocks (wait=0). So this might be a bug in the wait=1 case.
https://git.rtems.org/rtems/tree/cpukit/score/src/coremsgsubmit.c?h=4.10#n132
By manual code inspection, I think POSIX mq_timedsend goes through the wait path. But there is no wait path for classic message queues.
The question also arises whether this use case should be supported for classic mqs: Block on send() with timeout when mq full.
