[ECOS] Why does cyg_thread_delay() not return?

[Judong Kim]

Hi everyone!!

I am working on network equipment, ecos-1.3.1-cvs and mpc850.

My problem is that cyg_thread_delay() function does not return, exactly Cyg_Scheduler::unlock() in cyg_thread_delay().
But this is not all the time happened. Just, when network packets are flooded.

Now, I guess this is because of some kind of interrupts. But I am not sure.

Please, can anybody give some helps!

Thanks in advance.

regards.
