Max sendq excedeed between hub and leaf

[RoTT]

Hello,
i have a big problem.
In our network we have closed all international connection and only local people can connect in my server.
So, from 4 days i receive this error between hub and leafs max sendq excedeed 50023(50000) and if i increase sendq under class servers to 100000 i receive 100044(100000) for excaple.
I see in the log of server that is a flood of irc connection but if i put in my unrealircd.conf the code that the connection are closed for everybody except of nation connection... how is it possible?
Is it solved only with iptable?

One possible cause of this could be something as simple as ulines. Eg where services for example is not ulined on one server so that server bounces ever +o services sends for its bot on a channel, services then bounces a +o back and so on until the server without the uline for services gets disconnected for the error you receive.

A sendq of 50K or 100K is quite low in this case, I would suggest bumping it to 1M (1000000) or more. Just like the example server class has in doc/example.conf.

Jobe could still be correct, it could be a mode fight. You should be able to see this in channels and by other server messages.

Hello,
if i increase the sendq the error is:
Max SendQ limit exceeded for *.*.* [*.*.*.*]: 1000081 > 1000000
Max SendQ limit exceeded for *.*.* [*.*.*.*]: 2000047 > 2000000
Max SendQ limit exceeded for *.*.* [*.*.*.*]: 3000054 > 3000000
Max SendQ limit exceeded for *.*.* [*.*.*.*]: 4000072 > 4000000

i cut the Neostats uline but the problem persist.
P.s. my server connect with option automatic.

U:Line updates are not /rehash'able The server must be introduced as U:Lined or not. U:Lines are also case sensitive. Please double check all U"Lines on all servers to insure they are correct and match identically across the network Then restart and reconnect all servers affected. Then restart all U:Lined servers.

PS: NeoStats/Services must be U:Lined. So cutting their U:Line is making it worse/causing the problem.

Hello,
i checked everythings, the uline on leaf, hub, services... seems everythings ok... the problem persist.
I paste config of one hub and one leaf and services.
Can someone help me?
Services.conf http://pastebin.com/0ZGsdZLZ
Hub config http://pastebin.com/9Cx5SXPv
Leaf config http://pastebin.com/b4hLZULX

Thanks a lot!!!

ServerName "Services.Myserver.Net"

hub:

ulines {
Services.myserver.org.Net;
NeoStats.myserver.org.Eu;
};

Leaf:

ulines {
Services.myserver.org;
NeoStats.myserver.org;
};

Once again, U:Lines *MUST* match exactly and are case sensitive.
