Description
Hi ,we are running a mongo shard environment which includes 3 mongos servers, 3 config servers and 3 shards with replica sets.Recently we see some abnormal slowness in queries.as well as we encountered the below log which shows information that inconsistent update.this was encountered multiple times we need your opinion on this to resolve out this issue.also need to know whether this continuous occurance will leads to performance hit in the mongodb.
