I found it out myself.
strict_maxclient was set to 1 and maxclient was reached
so, vmm freed pages within the filecache. Works as designed

Subject: minfree default


Hello,

I have problems in determining the minfree default.

As far as I know its 960 * number of processors * number of mempools.

Page stealing starts when minfree is reached. I tried to confirm this on a =
test node and that run fine (I did a dd </dev/zero >some_file in another se=
ssion to fill up the filesystem-cache):

That looks reasonable. Page-stealing (fr/sr activity) starts at about 2700.=
 There is one mempools and 4 processors (bindprocessor -q).

However, on all "big" systems minfree seems to be much higher than it shoul=

Here I have 4 processors and 5 mempools. 4*960*5 gives 19200. However, minf=
ree seems to be at about 180000.

Other system:

Here I have 2 processors and 4 mempools. So, minfree should be 7680 but see=
ms to be about 210000.


vmo -o mempools gives 960 on all systems.

Can anybody explain?
