Recent nVidia GPU drivers (460.x and 461.x) have an issue in the NVLM library, causing any application using it to monitor the power usage to leak memory. This can affect Awesome Miner, Remote Agent and a number of mining software.
On the system affected, the process reading the power usage will consume more and more memory over time.
Workaround: Older nVidia GPU drivers, for example 457.x, doesn't have this memory leak problem.
