When setting some units to mine XUN again, I noticed that the connection kept being rejected after I had already gotten a few of them ready. After checking the previous units that I had just set up and were successfully mining, I saw that they were now having their shares rejected by the pool.
I created a new wallet and started moving the units to mine with the new address and while setting them up, they again started being rejected. Out of frustration, I created 12 new wallets and gave each unit an individual wallet to mine to. After checking again the next day, 8 of the 12 were now having their shares rejected.
This entire setup was mining flawlessly to my original wallet a few weeks ago and nothing has changed between then and now that I can think that would cause this. I switched to mining XMR for a period, but wanted to switch back to mining XUN. The only change was in the config to point at my XUN wallet and pool, rather than the XMR wallet and pool.
These are all CPU miner units and no overclocking has been done. No GPUs are used in this setup.
xmr-stak is the mining program I am using and the message it is giving me is something along the lines of:
Fast-connecting to alpha.ultranote.org:7777 pool ...
Pool alpha.ultranote.org:7777 connected. Logging in...
SOCKET ERROR - [alpha.ultranote.org:7777] Whoppie ! : (
SOCKET ERROR - [alpha.ultranote.org:7777] RECEIVE error: socket closed
Please help me sort this out or am I going to have to abandon participation in XUN mining
