      Description

      We are experiencing high CPU, above 90% on the primary server of a replica set. The server is only hosting MongoDb. We have 3 servers, primary, secondary, and an arbiter in our production environment. There are a few databases. The total data size in all databases is very small. Our mongodb instance is datastore for a .NET web application. We are using the C3 driver, version 1.8.1. Connection string: mongodb://TMPTBCACHE01P,TMPTBCACHE02P/?replicaSet=TMPWW;readpreference=primaryPreferred
