Hi folks,
I noticed something unusual on my home desktop machine (K6II, 448M RAM, runs
KDE, samba, nfsd. 2.6.12-rc2 on Debian sarge). The machine seems to feel
slightly sluggish; it seems to swap a fair bit more than it did under
2.6.11, but at the same time it's not actually using more swap that it used
to. The large numbers are slowly growing larger too. The biggest spamd was
only 156% of memory yesterday. Normally it's only my xserver (and
occasionally konqueror) that manages to grab more than 10% of memory...

pmap output seems normal too (total ~40M).
Any ideas on what's happening? Or is everything actually normal and I've
just made an incorrect assumption somewhere? (in which case I'd like to know
what definition of 'resident' I'm supposed to be using :P)
Thanks,
-MD

FWIW, me too :P
I think there is a memory leak in recent 2.6.12 kernels.
At least on my desktop there is (although it has some of
my own patches and I've been too lazy to do more work on
it so I haven't reported it).
It seems to be leaking `size-4096` slabs somewhere.

No, another one. Much faster. A few kernel compiles and I have
to reboot (only 256MB RAM, though).
But as I said, not quite a vanilla kernel. I'll have to get
motivated and compile a plain one and try to work it out. I
was hoping someone else would do it ;)
