The first machine has a many of directories containing many thousands for files. BTW could anyone enlighten me to the exact meaning of the values in the slabinfo gile.

Regarding this issue, I have a similar problem if I do a free on my system I get : --- total used free shared buffers cached Mem: 1157444 1148120 9324 0 22080 459504 -/+ buffers/cache: 666536 490908 Swap: 641016 19072 621944 --- Now what I do a ps there seems no way to accound for the 500mb + of memory used. No single or group of processes uses that amount of memory. THis is very disconcerting, coupled with extremely high loads when cache is dumped to disk locking up the machine makes me want to move back to 2.2.19 from 2.4.3. I would also be curious to see how the kernel is using memory...
