There is internal queue of messages in the mpd-5.5 with length 8129.
Messages are generated based on various events and enqueued there, then
processed.
Mpd uses GRED algorithm to prevent overload: it accepts all new L2TP connections
when queue has 10 or less slots occupied (unprocessed events).
It drops all connections then it has over 60 slots occupied.
s/all/new incoming/
In between, it drops new message with probability equal to (q-10)*2 percents
s/message/L2TP connection/
where q is number of occupied queue slots. These constants are hardcoded in its
src/ppp.h
Each time it decided to ignore incoming L2TP requests it notes that in the log,
as you have already seen.

Hi Eugene,
if I undestand corectly, in order to increase the connection rate I need
to replace 60 with 600 and 10 with 100 like this:
#define SETOVERLOAD(q) do { \
int t = (q); \
if (t > 600) { \
gOverload = 100; \
} else if (t > 100) { \
gOverload = (t - 100) * 2; \
} else { \
gOverload = 0; \
} \
} while (0)
Is this enough, or I need to modify something else ?
