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.

Hi madhawa.niranga,

Thanks for your report. Please note that SERVER project is for reporting bugs or feature suggestions for the MongoDB server. For MongoDB-related support discussion please post on the mongodb-users group or Stack Overflow with the mongodb tag. A question like this involving more discussion would be best posted on the mongodb-users group.

Please be aware that MongoDB 2.4 is no longer supported and MongoDB 2.6 will not be supported beginning November 1st. Therefore, I would strongly recommend that you consider upgrading to a more recent version to take advantage of numerous improvements and bug fixes.

Kind regards,
Thomas
