We have a replica set of production mongoDB 3.6.10 , large volume of 5.5 TB , over 10,000 connections anytime , applications read both from primary and secondary servers , we see almost every month a crash in the primary server while every month we see increase in the non-mapped virtual memory. Is it recommended to do a planned restart every month in order to clean the non-mapped virtual memory and to avoid server crashes? Thanks alon

  • Hi Alon,you should look into what is causing the issue are you using to many map reduce queries which is increasing the load, restarting the services should be the last resort. – Priyanka Kariya May 29 at 7:12
