I didn't make it!
i don't know my game just crashes and gets this error: (Repeat): Z_Malloc(): Failed to alloc 4194304 bytes (TAG_TEMP_WORKSPACE) !!!!! wth? and its happened before, so how do i stop that from ever happening again?
try removing recent PK3s and also remove any things you have downloaded for JKA
It's saying it can't get enough memory to do something. What are you doing when you get the error? And, as shadow said, try removing a few PK3s.
