Something weird happened tonight on one of my two rigs. Early this morning I noticed on ethermine.org that one rig with 8xRX 480 cards did not work for about 5 hours.
I approached the rig and, surprisingly, noticed that he worked steadily since the last restart I did about 8 hours before.
I checked the log file and I realized that there was no errors or restart in it. I reviewed the Task Manager and found that PhoenixMiner.exe on this rig uses about 887 MB of memory, which is roughly 441 MB more compared to the 8xRX 580 cards running steadily on ethermine.org, practically twice as much memory.
I restarted the rig and he reappeared at ethermine.org, but I noticed that after 5 minutes of work PhoenixMiner.exe used 558 MB of memory and after 8 minutes 887 MB of memory again.
I do not know how the Phoenix miner could work permanently, and that ethermine org shows it does not work. This is not about any kind of hacking on the side, I think the problem is in the miner itself, maybe it's a bag in the miner. I'd like to hear your suggestions.
