Allocated heap space bug(?)

[lordarrani]

Since the latest update, I've been having an issue when I try to run any modpack. The launcher loads up perfectly well, but whenever I hit play the modpack fails to load, resulting in the following error. 

[B#339] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
[B#339] SLF4J: Defaulting to no-operation (NOP) logger implementation
[B#339] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

[B#339]  Error occurred during initialization of VM
[B#339]  Initial heap size set to a larger value than the maximum heap size

Of course, I initially assumed that I could fix it by changing the java args, but that didn't work.

 

If anyone's run into this before or knows how to fix it, I'd really appreciate the help.

At the end of your log, there is this line:

[B#339]  Picked up _JAVA_OPTIONS: -Xmx512M

The problem you are encountering is caused by a java environment variable which limits all java processes to 512 MB max.

Even though you might think to prevent this by just ramping your RAM usage up in the launcher, this environment variable just happily overrides that.

Please join the Technic discord chat, and ask in the #help channel how to remove the Java environment variable. This happens quite often, so no worries.
