Description tang ming 2012-09-17 12:40:31 UTC 
Description of problem:
   Last days,we created two lxc containers on one host(host hardware:HPDL360G7,memory 24G,RHEL6.2,X86_64),we run a java application in one container ,we meet oom-killer unfortunately,but at that time,the lxc container still had 1G pagecache and 1G swap sapce,we thought it is a bug!
   Our colleague added some code  in its kernel code and rebuilt and run it,we found its something wrong at mm/huge_memory.c do_huge_pmd_wp_page() function call
   Our host had THP on,we see that if we turn off THP,it will not call this do_huge_pmd_wp_page() function,and we did so,it run well as expected.
   At last we found a patch in linux kernel websit which fixed the problem at newer kernel  ,and after we used the patch,it run well as expected too.the patch address is 
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=1f1d06c34f7675026326cd9f39ff91e4555cf355
   We found this problem also exists in RHEL6.3(X86_64),so we report it hope you can fix it as soon as possible.
