Out of memory on 16gb ram, PAE 32bit 2.6.23
I got 16GB ram in my shiny new box, but since the application Im running only supports 32bit os I have to run PAE to access all of it (porting it to x86_64 will probably take forever)
After a while it seams that Im running out of lowmem. Ive tried various kernels/kernelconfigs from Fedora7 default to 2.6.23.
It starts fine with 500mb free lowmem but after some hours it has worked itself down to 9mb free, then it varies between 7mb and 9mb for the remainder of the day until i oom-killer starts killing all my processes. As for highmem I dont use more than a few hundred megs, the rest becomes disk cache.
Any experience, any remedies, any tricks I might want to try?
