Finally, we found the root cause, it is kernel issue with specific version on ubuntu 14.04.
We prepared new environment for testing, 3.3.8，3.5.11，2.7 on ubuntu 12.04 and 14.04. 3.3.8，3.5.11 on ubuntu 12.04 is ok 2.7 on ubuntu 14.04 is ok 3.3.8，3.5.11 on ubuntu 14.04 is abnormal. We tried several methods, finally I found this https://bugs.launchpad.net/ubuntu/+source/linux-meta-lts- trusty/+bug/1516738 and I downgraded kernel version to 3.13.0-57 on ubuntu 14.04, memory usage is normal now. I don't know how was it introduced into kernel on ubuntu 14.04, but it is really works for me.
