Ok, done sooner than I thought. http://kuoi.asui.uidaho.edu/~wes/debug/ The runlevel 5 ones aren't from separate boots, I just telinit 5'ed after grabbing meminfo and slabinfo. And the dmesgs are really from /var/log/messages, but who's counting. (And yes, I know /dev/hdg is dying, no system stuff on there) Unfortunately, I don't know the significance of (m)any of the entries in the slabinfo, although I do note that dentry_cache accounts for roughly 10 MB of the difference... Hopefully some kernel gurus can tell if this behavior is a problem or not. Or maybe a side effect of debugging stuff? --wes
