After upgrading my mythtv system from 2.6.11-1.1369_FC4 to
2.6.16-1.2069_FC4 from atrpms I see the slab memory
usage increased from 13MB to 214MB.
Something must be wrong here. This is a pretty standard
MythTV box. Reiserfs with a volume group, PVR-350,
M179, geforce NVidia card, Athalon cpu, 256MB memory.
Does anyone else see this kind of memory usage from
slabtop on the 2.6.16 kernel.
Any idea other than building a custom kernel
how I can track down who has used this memory?
It is pretty early in the boot process (before
/etc/rc.d/init.d/syslog is run).
