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]: coreservicesd(89,0xa0220fa0) malloc: *** mmap(size=16777216) failed (error code=12)

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.

vmmap lists the virtual memory ranges that have been mapped you could do a little math to figure out what is available. -Shawn _______________________________________________ Do not post admin requests to the list.
