Hi there, We have a problem with our ES cluster. (see the attached screenshot) As you can see there is a node on red 99% CPU, and it changes from time to time, I mean there isn't only one server on 99%, one can "calm down" another is stressed up and raises to 99% CPU. I have attached also an `htop` for the stressed server. The slowlog does not show anything suspicious though some respunses take more than 3 seconds to complete.
