Unknown Command Exception error

Hi all ,I am facing one strange problem .We found that one of the database is missing from the serverA. we created a replica copy from the cluster (ServerB)This is a web based application and when we are trying to access the application on serverA then system is throwing “HTTP Web Server: Unknown Command Exception” then path of Java script file .Like HTTP Web Server: Unknown Command Exception/a/b/c.nsf/xzy.js

I chceked all the profile documents and java scripts libraries all are fine.

Could some one let me know what to do in this one?

The problem is the URL being used to access the file – specifically, the query string. If there is a query string, the first thing in the string MUST be a valid Domino server command (like ?Open).
