      Description

      MongogetCmdLineOpts.txtrsStatus.txtserverStatus.txtbuildInfo.txthostInfo.txtgetCmdLineOpts.txtcollStatsLocalOplog.txtDB memory usage very high 75%. For Mongodb01. Mongodb02, Mongodb03 Available Memory went down to 48%, 29%, 31% from 67%, 46%, 50% respectively throughout the load testing of 15 days. Are there chances that memory usage goes to 90% and process may kill. Why it is not returning free space to OS??
