MongoDB eats 100% CPU when idle I am running in OpenVZ container with Ubuntu 14.04 LTS.

MongoDB version:

db version v3.0.4
git version: 0481c958daeb2969800511e7475dc66986fa9ed5


I use clean installation like described here - http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/

top shows around 100% - 150% CPU 

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
30480 mongodb   20   0  548096  66920  39884 S 150.2  1.6   4:55.38 mongod


This is while nothing else is going on. Nothing else is running in the container. No queries, no connections.

I have tried lock file in this question: https://stackoverflow.com/questions/10747580/mongodb-service-at-100-cpu. It's not it.

Edit2 more detailed logs

A log with journaling enabled: pastebin.com/kKx4SJ98

Journaling disabled: pastebin.com/s2GT71w7

With journaling disabled the CPU usage cuts in half (around 40% - 80%). This all when idle.
This is the same issue as described here (for MySQL): High CPU usage from MySQL with no queries at all running

sudo date -s now


Caused by leap second and a bug in the kernel.
