Subject: Re: detecting kernel mem leak

Hi,

I kept my kernel running with few applications for 5 days , doing
nothing more than backing up few kb of data on disk and refresh few X apps.

Ater five days the global memory available go down from 24Mb to 8Mb ...

The are some signifiant changes in slabinfo but now, I do not know where
to search ?

active_jobs :
proc_inode_cache : 150 -> 299
radix_tree_node : 807 -> 870
dentry: 4092 ->4249
buffer_head: 1138 -> 4824
pid_1: 64 -> 76
size-64 : 885 -> 944

memory BEFORE          AFTER :

MemFree:          24324 kB.................8692Kb
Buffers:              3956   kB...............18740Kb
Cached:             34080  kB................34452Kb
Active:             131176 kB................147592Kb
Inactive:             26708 kB..................25440Kb

Slab:             4692 kB........4952kB

SReclaimable:     1480 kB ............. 1744kb
SUnreclaim:        3212 kB...............3208kb



in the ps tree only Xorg SHR memory growed from 5592 to 5612
