Actually, i'm running orca as server-process on 4 Linux-boxes for about 154
days without interruption and any problems. I used Perl 5.8.0 from CPAN and 
compiled a version to use with orca only, to make it easier to distribute it
to 
other boxes. The orca-version i used was 0.27 (Downloaded it in Jan.).
In the following i grapped the output from an ps i started on all boxes:

calc1:~ # ps -eo pid,user,rss,rsz,sz,args | grep orca

Nearly all orca-processes are running for about 154 days now except 1, where

i inserted web-monitoring into procallator.cfg after my procallator-addon
for
webmonitoring was ready. this one is running on calc5 for about 30 days. The
differences between the single process-sizes results in the fact, that the
single
processes calculate data for a different number of hosts with a different
number
of graphs generated. System calc1 and calc2 monitor the same # of hosts with
the difference that calc1 monitors an E10K with 10 qfe cards and about 8
other 
hosts with at least 1 qfe-card and many reconfigurations to the mounted
volumes.
Calc2  doesn't have this problems with the changed volumes and no qfe's to 
calculate, so that the # of calculated graphs is much lower in comparison to
calc1.
As i asume on these values the memorysize depends at least on the number of
calculated graphs: calc1 calculates about 34% more graphs than calc2, 250%
more than calc3 and about 500% more than calc5.

Here i got the output of /opt/DRGorca/perl/bin/perl -V:

Maybe you have to compile your own perl for your 2-CPU box to use it
with orca. I'm sorry that i don't have access to an x86 multi-CPU box to 
verify this issue. 

Hope, you suceed with this!
