Memory limit parameter not working ?

Looks like its an issue when using the Nicehash stratum protocol, which is currently assigning Ethereum at the beginning of mining for a second before switching to the proper coin. I'll have to look into the issue more.

In the meantime, you can switch to the EthProxy stratum protocol to avoid the issue. Also, I'm seeing weird behavior with ethminer on EthProxy and see that it hasn't been updated since 2019, so I'd recommend switching to a different miner as well.
