I've done one more test. I've run esd with: $ strace 2>/tmp/debug esd And then I've run on the another console: $ esdrec > /tmp/test.raw Then I've killed esdrec with CTRL+C (after a few seconds). In the /tmp/debug I've found:

So it seems, that ESD is waiting for input from the client!!! (And as I've stated in my previous post the client is waiting for input
from the ESD).
It seems that there is a kind of deadlock there :-(...
