[RFC] Reproducible OOM with just a few sleeps

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Dear Linux-MM,

Seems that any i386 PAE machine will go OOM just by running a few
processes. To reproduce:
  sh -c 'n=0; while [ $n -lt 19999 ]; do sleep 600 & ((n=n+1)); done'
My machine has 64GB RAM. With previous OOM episodes, it seemed that
running (booting) it with mem=32G might avoid OOM; but an OOM was
obtained just the same, and also with lower memory:
  Memory    sleeps to OOM       free shows total
  (mem=64G)  5300               64447796
  mem=32G   10200               31155512
  mem=16G   13400               14509364
  mem=8G    14200               6186296
  mem=6G    15200               4105532
  mem=4G    16400               2041364
The machine does not run out of highmem, nor does it use any swap.

Comparing with my desktop PC: has 4GB RAM installed, free shows 3978592
total. Running the "sleep test", it simply froze after 16400 running...
no response to ping, will need to press the RESET button.

On my large machine, 'free' fails to show about 2GB memory, e.g. with
mem=16G it shows:

root@zeno:~# free -l
             total       used       free     shared    buffers     cached
Mem:      14509364     435440   14073924          0       4068     111328
Low:        769044     120232     648812
High:     13740320     315208   13425112
-/+ buffers/cache:     320044   14189320
Swap:    134217724          0  134217724

Please let me know of any ideas, or if you want me to run some other
test or want to see some other output.

Thanks, Paul

Details for when my machine was running with 64GB RAM:

In another window I was running
  cat /proc/slabinfo; free -l
repeatedly, and output of that (just before OOM) was:
