Re: [rules-users] What is contract between Heap Size and PermGen space
This is a pure java question not a drools question - I'd suggest you ask the experts
on one of the java or jboss mailing lists!
One question I'd have is whether you are running a 32 bit or 64bit jvm - if you are
running a 32bit jvm then you will have limits on how much memory in total a process can
address (including additional memory needed for the actual jvm, hotspot compiler etc).

Subject: [rules-users] What is contract between Heap Size and PermGen
space
In my server Ram is 16GB but when
1. I tried to set max heap size to 2048MB in run.bat file and when started
jboss server it thrown exception as "Could not reserve enough space for
object heap" it accepted max 1336 mb.
2. and also JBoss server did not accept more than 128MB PermGen space but
when I reduce the heap size from 1336 to 1024 it accepted PermGen space to
max 256MB.
Please let me know the reason when I have enough memory why it is not
accepting heap size as 2048 and what is contract between heap size and
PermGen space as reducing heap size helped PermGen space to increase.
