I asked for solution for my problem on VPS, not for buying a grafic card.
Anyone with solution?
Lots of VPS's will terminate mining tasks or processor intensive tasks, but it could also be the host OS taking the task down with an OOMkiller (out of memory killer). Typically speaking a VPS isn't well suited to processor intensive tasks.
It's not about memory, it have 16GB (enough for Monero), and I do not use max core power ( 8 ), I am using 75% ( 6 ).
It's Ubuntu and it have all it needs to mine XMR. I use the same config and miner on the other VPS and there is no problem of any kind. So it is kinda strange to me and thats why I am asking for help or solution.
