You can see how much the max heap is in the Solr admin UI dashboard -
it'll be the right-most number on the JVM-Memory graph. On my 64-bit
linux development machine with 16GB of RAM, it looks like Java
defaults to a 4GB max heap. I have the heap size manually set to 7GB
for Solr on that machine. The 6GB heap you have mentioned might not
be enough, or it might be more than you need. It all depends on the
kind of queries you are doing and exactly how Solr is configured.
Followup: I would also recommend starting with my garbage collection
settings. This wiki page is linked on the wiki page I've already given you.

You might need a script to start Solr. There is also a redhat-specific
init script on that wiki page. I haven't included any instructions for
installing it. Someone who already knows about init scripts won't have
much trouble getting it working on a redhat-derived OS, and someone who
doesn't will need extensive instructions or an install script, neither
of which has been written.
Thanks,
Shawn
