Hi, Blair,

Embarrassingly, I was running Orca build 411 before I upgraded to 522.  
When I upgraded to 522, I didn't touch Perl, and I'm using the RRD that 
came with 522.

I just took another look at my memory graphs, and I see now that that 
system was leaking memory since well before the upgrade to 522. Orca 
still might be leaking in daemon mode on this machine, but I think 
there's something else fishy about the box.  My other v210s do show a 
slow memory leak over time, but not nearly to the degree the Orca box 
demonstrates.  BTW, this box (npd-virga) is now running with the 
winallator SourceFile.pm patch I submitted recently -- it's possible 
that's contributing, but it wouldn't account for the leak shown in 
December and earlier (was using straight 411 at that time).

Yearly npd-virga Memory Free

I'll keep an eye on Orca's memory size for a while.  Though sadly, 
npd-virga's SE was stopped on the 10th (probably for the upgrades), and 
I didn't notice 'til today.  *sigh*
