My understanding was that the issue is Intel architecture related, not just Solaris specific. I seem to recall going down this path before but I couldn't find the definitive bug parade description; the one I cited above was the nearesty I could get. The bug description says: > SPECIAL NOTE: Does the documentation note the limitation of support > in win98/NT and some win2000 release? What about linux, should this > workas well? If a customer uses -Xmx3g on win98, do we tell them > that large heap support is not valid for this OS. which is sort of ambiguous as well though hints at the issue. My foggy memory recalls something about the Intel architecture not being able to reliably return contiguous large enough memory segments for HotSpot to do its job. Not in the related bug http://developer.java.sun.com/developer/bugParade/bugs/4401509.html that someone claimed IBM's 1.3.0 implementation was able to use more than 2gb. Also note that IBM recently released their 1.4.0 implementation: http://www-106.ibm.com/developerworks/java/jdk/linux140/ Don't know about BEA's JRockit off hand. -- Jonathan Doughty The MITRE Corporation [EMAIL PROTECTED] ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
