The answer to your question is probably on the kernel console. Try to
retrieve it with UART or network. And also tell us on which
architecture/board you have this issue.

Send us to us what the kernel console tell you... we can not guess what
the issue is if you do not send us information about it.

Also, the xenomai mailing list is an old fashioned mailing list where we
do not top post. So please, no top posting.

The error is on the first line of the logs:

[  111.023581] Watchdog detected hard LOCKUP on cpu 0
[  128.060170] BUG: soft lockup - CPU#1 stuck for 23s! [satch:2028]

Your program has spinned 23s without relinquishing cpu.

I changed the code with bounding  tasks running time with TIMEOUT. this time log says its a bug at task.c . why this is happening? is it a real bug?

Do you have the same bug if you sleep a reasonable time between sending
messages instead of sleeping 40 nanoseconds?
