-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I tried removing the flow and subjectively packet loss occurs a bit less often, but still it is happening. Right now I'm trying to figure out of it's due to the load on the server or not - I've left only about 15 concurrent recording instances, producing < 8% load on the system. If the packet loss still occurs, I guess I'll have to disregard the loss measurements as irrelevant, since at such a load the server should not be dropping packets at all... I guess.
