Since sometime after build 1176 (IIRC), I've noticed that the KDE System Monitor tray applet (/usr/lib/kde3/ktimemon_panelapplet.*) has been reporting unbelievable amounts of memory used by the kernel. I finally got around to taking a gander at the source to figure it out... in KSample::readSample() in kdeaddons-3.3.2/kicker-applets/ktimemon/sample.cc, it adds the Slab: line (if it exists) to the Buffers: line to estimate kernel memory usage. Seems reasonable to me. So I compared those values as reported by two different kernels. Under 741 (current FC3 update), meminfo says: Buffers: 21676 kB Slab: 24252 kB Which I can believe. But under not too different usage, 1124 (latest rawhide) reports: Buffers: 8052 kB Slab: 116104 kB Which seems crazy (this is a 256 MB machine). So, has the meaning of the Slab: line changed, such that I need to bugzilla this for kdeaddons, or do I need to report this against the kernel? --wes
