Looking at this page https://stackoverflow.com/questions/13685402/how-to-assign-more-than-1gb-to-netbeans-jvm
I suggest setting this parameter to see if you get the corresponding error message. when I set -J-Xmx3024m I obtain these messages: /opt/netbeans-7.2/bin/netbeans Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine.Error: A fatal exception has occurred. Program will exit If you do then you know you are in the right place. This text suggests you can play around with the size. The message Could not reserve enough space for object heap means that 3024 MB is not available for assignment. Try reducing it Then you try this as suggested. netbeans_default_options="-J-client -J-Xss2m -J-XX:PermSize=512m -J-XX:MaxPermSize=512m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Xms2148m -J-Xmx2148m -J-XX:+UseParallelGC" On Sun, 20 Dec 2020, 16:25 Oliver Rettig, <oliver.ret...@orat.de> wrote: > Hi, > > > > I remember also got such messages in the past during opening big text > files in my netbeans-platform applications and with increasing heap-size I > cauld not get rid of the message.
