Factorio Forums

Running command /delete-blueprint-library everybody confirm on a map with a big offline player blueprint library does not reduce ram usage on linux.

Load attached map on headless linux.
Connect windows factorio to linux factorio server.
Run /delete-blueprint-library everybody confirm
Ram usage of factorio on windows immediately decreases from ~8gb to ~3gb. Ram usage of factorio on linux stays the same unless save is reloaded.

I tested non headless linux and it appears to have the same behavior as headless.

Thanks for the report. This is related to how linux programs manage memory (it will not release memory back to the OS unless you explicitly ask it to). I added the explicit request when deleting blueprint libraries for 2.0.
