MongoDB constantly high cpu usage : <p>According to docker container statistics, my mongo database consumes constantly between 250 and 350% cpu. That's pretty impressive since it's a single core system :P</p>

<p>The sad part is that this is my production instance and much more sad is that it has to live until the next prod-backup and thats 3.5 more hours to go.</p>

<p>I tried to do a mongotop but it tells me 0ms stats for all shown collections. Can I do anything else to figure out what's going on?</p>

<p>PS: The db is up for 9 weeks and didn't cause problems.</p>
