Hmm, yes, now I see it. I've added logging of thread_pool.num_queued value
(btw, this is very important to be able to see as in the logs as it changes)
and now I see that 256 threads just not enough for this configuration and load
as thread_pool.num_queued spikes upto about 800.

I'm back to 1000 threads and this keeps thread_pool.num_queued under 2 for now.

Thank you for explanations and patience.

I'm afraid that changing freeradius core is out of my skills and limited
by lack of familiarity with the code.
