Dear Björn,

I have encountered with a transient problem when I run an application with parallel real-time tasks using pthreads. Sometimes the tasks’ job are not released in correct time. You can see the problem in figure below, the second job of the last task is released at 13ms instead of 10ms!
Do you have any idea where this problem comes from?



Best Regards,
Sobhan Niknam
