[Bug 1488049] Re: ubuntu14.04(3.13.0-37.64), kernel crash (mapcount 0 page_mapcount 1)
** Description changed:
Bug Description:
this issue（mapcount 0 page_mapcount 1） has already been resolved by 3.13.0-36, but this bug arised.
memory usage is close to 100 percent.
Here is I believe the first record in syslog when it starts:
