High memory kernel support

[Charles Farinella]

 	I have a server that started throwing the following error the other
day:

kernel: __alloc_pages: 0-order allocation failed (gfp=0x1d2/0)

We run some pretty memory intensive apps, and from looking at various
logs it appears the machine ran out of memory space and started shutting
down services.  I was able to stop and restart all of the server daemons
and free up memory.  Since then everything seems to be fine.

In researching the cause, I find that my kernel does not have high
memory support compiled into it (the default).  Now this is all a little
over my head, so I'm asking here, what do you think, will recompiling
the kernel to include high memory support resolve this?  The machine had
been up for 168 days before this happened.

It has 1GB of physical RAM, and 2GB of swap space.  Slackware 10.0.

Thanks,
