It is a armv5teb device with 32MB of RAM, 400+ MB swap on its 160GB USB2 root disk. The machine is used as a fileserver and to build packages for other ARM devices. It may be underpowered by today's standard but is a whole lot faster than my first Linux system (386sx20 with 4MB RAM) but the whole system with disk uses <8 watts and is silent. The problem comes when I try to untar a large file (in this case linux-2.6.23.tar.bz2). Regardless if I kill off every other process, eventually the oom-killer will appear and kill either the tar or the shell. I've tried every tuning option I and my buddy Google could find including (/proc/sys/vm/overcommit*) with no success. I'm not worried about paging impacting performance. I'd appreciate any help, pointers, or gentle taps with the cluebat. -Josh Error output to console: http://www.pastebin.ca/797155 config -> http://www.pastebin.ca/797206 slug2>$ uname -a Linux slug2 2.6.21 #1 PREEMPT Fri Nov 9 11:54:06 MST 2007 armv5teb unknown slug2:~$ free total used free shared buffers cached Mem: 30352 29124 1228 0 10196 9468 -/+ buffers/cache: 9460 20892 Swap: 465876 0 465876 cat /proc/swaps Filename Type Size Used Priority /dev/sda4 partition 465876 0 -1 slug2:~$ lsmod Module Size Used by nfsd 186556 8 exportfs 4320 1 nfsd lockd 51416 2 nfsd sunrpc 131952 2 nfsd,lockd reiserfs 255380 1 ixp4xx_mac 14644 0 ixp4xx_qmgr 5388 5 ixp4xx_mac mii 3424 1 ixp4xx_mac ext3 110472 2 jbd 47784 1 ext3 mbcache 5604 1 ext3 ohci_hcd 16804 0 ehci_hcd 30252 0 slug2>$ dmesg <5>Linux version 2.6.21 (josh@styx) (gcc version 4.1.1) #1 PREEMPT Fri Nov 9 11:54:06 MST 2007 <4>CPU: XScale-IXP42x Family [690541f1] revision 1 (ARMv5TE), cr=000039ff <4>Machine: Linksys NSLU2 <4>Memory policy: ECC disabled, Data cache writeback <7>On node 0 totalpages: 8192 <7> DMA zone: 64 pages used for memmap <7> DMA zone: 0 pages reserved <7> DMA zone: 8128 pages, LIFO batch:0 <7> Normal zone: 0 pages used for memmap <4>CPU0: D VIVT undefined 5 cache <4>CPU0: I cache: 32768 bytes, associativity 32, 32 byte lines, 32 sets <4>CPU0: D cache: 32768 bytes, associativity 32, 32 byte lines, 32 sets <4>Built 1 zonelists.
