Hi List,

I have a few queries regarding slab memory and it's usage.
I have seen slab cache increase by even 1GB, over two to three days on a 
stable system.(The system was sending and receiving bulk amounts of 
packets).
 
When is slab usually freed? Also when I analyzed /proc/slabinfo, I was 
able to see that the number of active slab objects were increasing mostly 
for task_struct, dentry_cache and proc_inode_caches. When are these caches 
allotted objects, in general?

Can anyone please explain the behavior related to slab allocation; or 
point to any reference material?

Thanks,
Sowmya.
