I've been using NB since version 4 on this computer (details below). However, just recently NB won't start; I just get "JVM creation failed".
So I set the heap space (after some experimentation) to -J-Xmx256m and it works.
But the netbeans.conf file says that the heap size is computed and you don't have to set it. It says if you want to find the current setting look in var/log/messages.log but I only have those up to version 6.7. Version hadn't produced one before I set the heap space manually.
This JVM problem has plagued my other IDEs recently but I've managed to fix those by lowering the heap space requirement (e.g. -Xmx512m).
So I have a more generic problem as well as one specific to NB. No, I haven't just lost 3/4 of my memory (although I am getting rather old).
Does anyone know why I need to change the heap space requirement?
Computer: 32bit Windows XP, SP3, 2Gb RAM, very little running by way of background tasks. Security patches up to date, Zonealarm Security Suite in constant use (I've checked "Program Security" -- JVMs are 100% trusted).
