Fwd: Re: memory usage - dentry_cache

[Marcin Kowalski]

To possbile answer my own question:
if I do a can on /proc/slabinfo I get  on the machine with "MISSING" memory:
---- 
slabinfo - version: 1.1 (SMP)
--- cut out
inode_cache       920558 930264    480 116267 116283    1 :  124   6
--- cut out
dentry_cache      557245 638430    128 21281 21281    1 :  252  126

while on an equivalent server I get 
----
labinfo - version: 1.1 (SMP)

inode_cache        70464  70464    480 8808 8808    1 :  124   62

dentry_cache       72900  72900    128 2430 2430    1 :  252  126

----

Notice the huge size of the inode and dentry caches. bareing in mind that 
both have 85GIG Reiserfs Home filesystems. 
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
