Both the 32 bit versions of windows and linux suffer from a maximum memory usage by a single process of 2GB. It's possible to get around this in linux by some kernel hacking but there are trade offs. So while not a hard and fast rule you're unlikely to be able to use over 2GB on a 32 bit machine.

A JVM implementation could queue the extra heap memory to a swap disk just like an OS can. But the performance tradeoffs are so bad - that writing such a jvm would be a bad idea. ;) -Tim Bruno Georges wrote: > Hi Tim > Correct me if I am wrong, but there is a limit of 2GB in a 32bits > architecture . > With Best Regards > Bruno Georges > > Glencore International AG > Tel. +41 41 709 3204 > Fax +41 41 709 3000 > > > ----- Original Message ----- > From: Tim Funk [EMAIL PROTECTED] > Sent: 05.12.2005 12:48 > To: Tomcat Users List <users@tomcat.apache.org> > Subject: Re: memory limit for tomcat? > > The JVM heap can be as large as you want it.
