How can I find what is occupying my low memory on 32 bit Linux OS?

cat /proc/meminfo |grep Low
LowTotal:         812908 kB
LowFree:           43340 kB

Regards,

  • `free` will tell you. But it's also in all the other fields in `/proc/meminfo` that you ignored with your `grep`. Most likely, it's page cache. – David Schwartz Oct 15 '12 at 23:09

Low memory (aka ZONE_NORMAL) is all kernelspace. It will be for things like kernel modules, buffers for your network and storage devices, filesystems, and pagecache.

You can cat /proc/slabinfo to see detailed usage.
