Hi,

we face a problem with on of our linux SLES Database Server. The kernel is consuming 80% of the memory for the slab.

SLES 11.3

Linux 3.0.101-0.21-default

MemTotal: 12195516 kB  
MemFree: 219028 kB  
Slab: 9364632 kB  
SReclaimable: 6859668 kB

Normally the SLAB is reclaimable by kernel itself or by command

#\>echo 2 \> /proc/sys/vm/drop\_caches

But in our case the kernel do not free the space. So the databases are swapping blocks to the hard disk.

Does anyone see some behavior like this in the past ?

Does this maybe a kernel bug ?

Is it possible to limit the slab ?

Thanks a lot !!!
