Over the course of several days, if ESET Endpoint Security 7.1.2045.5 is left running, it will gradually use up more and more memory, and ESET's ekrn process will climb to the top of the process usage chart in Task Manager, sometimes consuming up to 70% of the machine's memory by itself, even surpassing the memory usage of Chrome with 20+ tabs open. After just a few days of running, the computer becomes almost unusable, showing audio and video skipping and other symptoms of low RAM availability for other applications. This is all happening on computers running Windows 10 1803, with 8 or 16 GB of RAM installed, which is well within the hardware requirements.
When I uninstall Endpoint Security, the problem goes away.
I tested out version 6.5 something like a year ago, and reported identical problems to support, but the problem was never resolved. Hoping that it had been fixed a whole year later, I downloaded version 7.1, and it still seems to be having similar memory usage problem.
