Running this on the box after it's settled down a bit, (over the weekend, the usage hasn't altered), with all mail delivered and collected so the box is currently quiet, produces the following 'free' output:
root@plum:~# free total used free shared buffers cached Mem: 1029524 965344 64180 0 45204 22936 -/+ buffers/cache: 897204 132320 Swap: 2097136 116 2097020
And SysRQ+M yields the following:
SysRq : Show Memory Mem-info: Free pages: 66612kB ( 4424kB HighMem) Zone:DMA freepages: 4848kB min: 128kB low: 256kB high: 384kB Zone:Normal freepages: 57340kB min: 1020kB low: 2040kB high: 3060kB Zone:HighMem freepages: 4424kB min: 1020kB low: 2040kB high: 3060kB ( Active: 160155, inactive: 58253, free: 16653 ) 124*4kB 98*8kB 41*16kB 13*32kB 3*64kB 0*128kB 1*256kB 0*512kB 0*1024kB 1*2048kB = 4848kB) 11029*4kB 1097*8kB 140*16kB 7*32kB 1*64kB 1*128kB 1*256kB 1*512kB 1*1024kB 0*2048kB = 57340kB) 328*4kB 55*8kB 19*16kB 10*32kB 2*64kB 3*128kB 0*256kB 1*512kB 1*1024kB 0*2048kB = 4424kB) Swap cache: add 48, delete 24, find 13/14, race 0+0 Free swap: 2097020kB 262128 pages of RAM 32752 pages of HIGHMEM 4747 reserved pages 20447 pages shared 24 pages swap cached 0 pages in page table cache Buffer memory: 44424kB CLEAN: 209114 buffers, 836405 kbyte, 188 used (last=209112), 0 locked, 0 dirty ^^^^^^ Is this our magic value?
