I need some help with the claymore miner:
I have a setup with 4 MSI Radeon RX580 Armor 8G OC cards in Linux Ubuntu 16.04.02 using AMDGPU-PRO 17.10 drivers and claymore 9.3 software, 8GB Ram + 8GB swap. 2 cards are directly on the MB (x16, x4 PCIe) and 2 with risers (x1 ==> x16).
The system starts fine and mines for 16-20 hours without problems, all cards run fine.
Suddenly, without any errors on the console or the logfile, 3 cards drop out and only one card continues mining.
Then, claymore miner restarts automatically, now all 4 cards are disfunct and it delivers
OpenCL error -61 - cannot allocate big buffer for DAG
because for some reason, it doesn't recognise the full 8GB of the graphics cards memory any more, but only < 2GB. Strange.
After a reboot everything comes up normally for another 12-20 hrs.
Can somebody point me to a possible solution?
Thanx for support!
here's console output from first startup until mining starts, then at the time mining stops and the miner restarts again:
