Hi,

For more redundancy i had created 5 config server process in 5 different machines, and added the 5 config server information in mongos process.
When i try to start mongos process, mongos process is failed to start with the below error

Mongos server process:

1. mongos --configdb host01:47720,host2:47720,host3:47720,host4:47720,host5:47720 --pidfilepath /var/run/mongos-57720.pid --port 57720 --fork --logpath /var/log/mongos-57720.log --logappend --quiet
   Mon Dec 9 07:15:55.921 need either 1 or 3 configdbs
   #

I did not find any error or any other logs updated in the mongos logs, straight away it's though "need either 1 or 3 configdbs" message on screen and exit.

Config servers active and running

I am not sure why mongos process is not starting, mongos process will it allow maximum three config servers only?

Could you please let me know why its not allowing to add more than 3 configdbs?

Thanks & Regards
