Hi Team,
When we upgrade mongos from 2.2 to 2.4. The process running with --upgrade does not completes, it keep runnign for ever and we have kill or teminate it and then start it again without --upgrade option.

While in case of upgrade of mongod instance --upgrade process comes out of its own and once it comes out we start it again.

Want to check if this is normal behaviour of Mongos or our mongos process is getting hanged. I have attached the mongos upgrade logs file.
