Hey Claymore, on your ETH dual miner there is an argument: -ejobtimeout 1. Why we don't have it on CryptoNote miner? It is necessary when using unstable connection, for example 3G/LTE modems. 2-3 times a day there is a situation when modem reconnects to the cellular network (it may be that ip address is switching) and pool connection become broken, but miner still thinks it is ok and sends shares to the pool but the pool is not responding with accept or reject. The better solution would be to reset a connection if there is no response from the pool.
i mine with usb cellar modem (3G EVDO with verizon)) and dont get this with any of my miners. and i dont have that flag set on cdm, and no special flags on my other miners, had this 3g/evdo setup for years. running dstm, ccminer, ewbf, cdm, no issues, even back when gpu btc mining with cgminer. it might time out for a minute maybe but all miners always come back and shares are accepted normally..
maybe its a setting your router or usb modem? i had to use a special router for my usb 3g modem. or maybe its the pool doesnt like it? using mhp at the moment, and nicehash before they took a digger.
How many rigs do you serve with 3G modem? I have 15 rigs connected through modem and I have no idea how to solve this problem. The pool is nicehash. If I use cable internet connection, I have no problems. But I can't use cable on current location.
