bitcoin.exe/bitcoind.exe on win32 and more than 9 miners

[spiccioli]

Hi all,

is there someone here using bitcoin as a server on win32 to solo mining with more than 9 miners?

I'm trying, but it dies after  a few hours/minutes with an exception.

This is on a windows xp pc.

Any help appreciated.

I had no problems with 10 miners/about 4Ghash/s with server ip put in DMZ, read some logs, it could be memory failure, overheating cpu, bad NIC, bad NIC drivers, missconfigured router, lack of free space on c:

I was running 0.3.2x something, but 10 to 20 connections is too low, no idea how v0.4.0 is done, but I was getting like at least 50 to 70 at a time

Does this maybe have something to do with the XP 10 half-open TCP/IP connection limit ?
Apply one of the many available (re-branded LVLord scripts or whatever) TCP/IP Patches and nuke the 10 half-open limit and up it to 100 (or something close to that) and see if that helps.

What does your bitcoin.conf file look like ? What is the MAX RPC Connection limit ? RPC Timeout Value ?

My 'Solo Server' is also a Windows box, but in Server 2008 32bit flavour and I run 15+ cards, with 2-3 threads per card (using CGMiner) to it without any problems, although it took me some time to fine tune things - but it works great now.

Start with the basics above and make sure all bases are covered.

Hi bitlane,

no, it is not the 10 half-open tcp/ip connection limit, I did increase that limit to 256 with no differences at all.

You can see my .conf file here:

In the end I installed a linux PC and now everything works ok.

Thanks.
