I have a ton of these messages in the console for my DW20:
2015-02-15 07:27:40 [FINE] [ForgeModLoader] The world 44555c1b (world) may have leaked: seen 11295 times
The complaint I’m getting from the players is that the game is slow to the point of being unplayable. I haven’t heard of any crashes though.
There’s a proposed fix for Mac and Windows for actual leaks, not may haves, on the FTB forums, but I didn’t find anything Linux specific that I understood (I’m almost completely ignorant when it comes to servers).
Another suggested fix I found was to add -XX:MaxPermSize=256m to the start script (I’m guessing that’s ServerStart.sh in the server directory) but I’m not sure what that does. Right now there is a -XX:PermSize=128m but no maxpermsize.
I’m running MineOS Turnkey, Java version: 1.7.0_75.
General info question: ServerStart.sh has the line -Xms512M -Xmx1G. Is this the heap and if so would setting different values in the server.config section of the MineOS webui cause a conflict?
