Maybe I am completely off base here, but according to http://www.oracle.com/technology/documentation/berkeley-db/je/relnotes.html You must set the memory using a few different configuration properties. I searched the Freenet source and was unable to find: EnvironmentConfig.setCacheSize je.maxMemory je.maxMemoryPercent
Are you using a command or function other than these?
