i have 1 hub + 2 leaf. normally, each days, each split will be disconnected from HUB 3 to 5 times with a reson of "Connection reset by peer". befor this iam using default configuration which is;

class servers
{
pingfreq 90;
maxclients 10;
sendq 1000000;
connfreq 100; /
};

then, i change the setting to;

class servers
{
pingfreq 120;
maxclients 20;
sendq 3145728;
connfreq 100;
};

but, the network still splited 3 to 5 time each days. all server run on Windows 2000, and have a leased line (11Mbps to 45Mbps). iam running Wunrealircd 3.2.3 without SSL and all link using a zip protocol.

If you have a suggestion on how to reduces netsplit due to time out, please let me know.

"Connection reset by peer" can very easily mean an ISP issue.

He's right. Connection reset by peer for servers is in most cases just like a ping timeout. Thats what a netsplit is when 2 servers disconnect. So if you are having splits then the connection between those servers is not stable. One of the machines could be losing data from the NIC or it could be an unstable connection.

If you call your ISP they should have tests that they can run on your line that can verify the strenth of your signal. Also you maybe could try a couple simple pings to the server over a period of time to see if you have any packet loss.
