I'm seeing the same thing on my 16GB Mac Pro (early 2008, OS X
10.5.5). I'm getting crashes every few days in WindowServer or
coreservicesd; MenuMeters and Activity Monitor say I've got plenty of
available RAM (either unused or idle). system.log says:
system.log.0.bz2:Oct 29 14:35:19 macpro com.apple.coreservicesd[89]:

I suggest keeping top or Activity Monitor around and, when you see a large
growth in RPRVT or when VSIZE gets around ~3GB, capture heap / vmmap /
leaks
Thanks - that helps a lot.
Is there a way for me to keep an eye on the "largest contiguous block on the
free list", or something like that? I haven't done any dev on Darwin, so I
don't know much about debugging it.
