Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM
- by magneticMonster
I'm running a Java data import process on a 32-bit Ubuntu 10 PAE kernel machine. After running the process for a while, the oom-killer zaps my Java process. After some Googling and digging through docs, it looks like the system is running out of LowMem. I started the process for the third time and am watching free -lm show me Low: 464 386 77 with the free value (77MB) slowly decreasing.
Why am I running out of lowmem and how do I increase it?
Some details:
$ cat /proc/sys/vm/lowmem_reserve_ratio
256 256 32
$ free -lm
