How to find slab\'s usage?

[Tetsuo Handa]

Hello.

I was compiling Ubuntu 7.10's kernel and I encountered OOM-killer.

I saw /proc/meminfo and it seems to me that slab is leaking memory.
But /usr/bin/slabtop claims /proc/slabinfo is missing.

I couldn't continue the compilation before reboot.
I could continue the compilation after reboot.
So, I think this is a memory leak.
How can I find slab that uses so much memory?

Regards.
