Possible Memory Leaking on Scanning


Recommended Posts

Hi, I am using ESET Nod32, I noticed that after scanning my memory usage is super high. I am using a Window 10 desktop with 32G memory, before scanning the memory usage is around 8G, after the sncanning it went up to 18G. I rebooted and tried several times, and this situation can be reproduced after ESET scanning.

On the resource manager and procexp, it doesn't show any specific process used this much memory, so I assume it is related to ESET.


More info:

Hello @Nagato,

in case of a memory leak in the on-demand scanning, the memory would be allocated by the ESET Service (ekrn.exe), what is the amount of memory allocated by it after the scan completes?

I assume that the large memory allocations might be caused by caching of the files read during the scan by the operating system. There should be no issue with that, as when the memory is needed the content of the cache is released...

Please provide some screenshots to clarify where you are seeing the allegedly high memory usage by ekrn. Please take a screenshot of the whole tool window that you've used.
