Could not it be that the highest priority task is using all the CPU?
No, it's highly unprobable. The task runs at is should.
Is the low priority task also mapped as Xenomai task? In that case
calling standard Linux time services can be lethal:
Yes, the task is mapped as Xenomai task, because

Dear Sirs,
I'm using Xenomai with uclinux-dist-2008R1.5 on bf537.
Then, it is possible to use native api with a fdpic elf format?
I receive warning like relocation references a different segment.
I compile with bfin-linux-uclibc-gcc -lnative.
In my code I create 2 real time tasks.
All

Dear Philippe,
thank you very much for your very fast answer.
Anyway, please consider that I'm newbie about the matter,
so,
where I need to write these lines?
I find in:
/mnt/uClinux-dist-2008R1.5-RC3/staging/usr/bin
the xeno-config command.
Then, I run:
./xeno-config --xeno-cflags

Now, the question is, do you realistically plan to write an application
which makes no syscall in its real-time loop?
Unlikely, but it may happen in case of programming errors. Anyhow, the
pthreads will run legacy code and it would be a pain to add
