Hello!
I'm testing what can I bring out from gnugk-2.2CVS with openCG.
I'm trying to make 60/90 calls with openCG but gnugk starts to drop
requests:
After ARQ/ACF (not right after) gnugk drops the call and I don't have a
clue why.

In logs I don't see any more information what caused this drop.
GK runs in full proxy mode (RTP).

I have only stop record accounting. Probably the bottleneck is not in
radius backend (test call's duration is some minutes and call dropping
starts sometimes after 30 concurrent calls).
gnugk runs on single Xeon 2.8GHz (HT enabled), 1G RAM, Gigabit Etheret
card (intel), linux-2.6.11 SMP, slackware.
Call generators are near to the server, ~3-10ms.
Could anybody help me finding out what is the reason of dropping calls?
Thanks in advance,
Tamas
