We run GroupWise 7.03 on SLES10 SP2 x64 (and before that on SLES 9 32
bit). I was advised to run this configuration by someone from Novell, but
reading through the documentation it looks to be an unsupported

From the Novell Online Docs: "GroupWise Administration Requirements
32-bit/x86 processor or 64-bit/x86 processor running in 32-bit mode"

Despite being unsupported I have not experienced any issues. I would like
to move on to GroupWise 8 now but I am concerned about this whole 64 bit
thing. Is the documentation out of date in specifying 32 bit OS support
only? Or does the above phrase simply mean that the software will only
run in 32 bit mode on a 64 bit platform? Or am I only hours away from
some major catastrophe!!! On the download page there appears to be
reference to a x64 version ...
"30 Jan 2009 - GroupWise 8.0 Hot Patch 1 Linux Full US and MULTI x86-64
Security Alert". So I am left totally confused as to the status of this.

I want to run a 64 bit OS moving forward as I have encountered bad issues
with SLES 10 on 32 bit platforms under significant load (admittedly only
when running NSS) so some clarification would be much appreciated.
