Hello, I have this interesting setup: some computers on a LAN running minerd connected to a litecoind on one "server" and this litecoind is connected to a socks4 proxy running on a machine on different network. It looks like working and miners use 100%CPU. I have litecoind started with -printtoconsole so I see the messages. So it goes like this, but sometimes a strange problem occurs - like it cannot find any nodes to connect to or they all refuse connection or whatever.


Code:

and here something goes wrong and continues like this

when these errors start appearing all miners connections are being refused and they stop working. litecoind getinfo shows connections:0. When it worked it was connections:8. Strangely it seems like restart of litecoind always helps, but this is useless if it randomly stops working like this and needs to be restarted Undecided When there is this problem I can still start minerd and connect to a pool, so I don't know. The problem was happening even when I tested it without proxy, so it used different network. Is litecoin network unstable or what?
Now when it happened it was connections:0 for about 3minutes and then suddendly it went to connections:1 and miners started to work again...but only for about a minute before it broke again. Any ideas? I don't think there is a problem with local firewall, because disabling it does not help...
Or is there some list of stable nodes so I could configure it to connect to them to avoid problems finding some available nodes?

CPU load in last 15.6hours...

Average 80% load, so it means 80% time mining...is this normal? Does it happen also for pools? Maybe my ISP is not litecoin network friendly or I don't know...

looks like it pretty much coincided with the "address spam" on the ltc network Smiley
