Servers usually don't have X11, so it won't work. You better use
-vm-display-null (and -vm-sound-null). Try squeak --help for further useful options (like tuning Cog).<br>>> <br>> <br>> I am trying to use the -headless switch. Good to know it is deprecated.

You can find it here: <a href="http://leves.web.elte.hu/squeak/cog17.tar.gz" target="_blank">http://leves.web.elte.hu/squeak/cog17.tar.gz</a> .

It started dumping a LOT to the Debug Console, then it froze, still at 100%, but no increase in memory now and it went (Not Responding) and greyed out the
