Subject: [Xenomai] SIGXCPU with rt_mutex_release
Date: Mon, 31 Dec 2012 18:32:31 +0100 [thread overview]
Message-ID: <50e1cc2fb40c67.12589971@wp.pl> (raw)
Hi,
I have met problem when I run OROCOS helloWord example. Xenomai generate SIGXCPU signal when rt_mutex_release(...) is called. I have installed signal handler for each realtime thread created by OROCOS and I get following result
SIGDEBUG received, reason 4: affected by priority inversion

There is much bigger mess during exiting from application. I am not pretty sure this is a Xenomai problem, if not sorry for bothering. I haven check it with previous Xenomai release yet.
Best regards and happy new year,
Mariusz
