TIBCO EMS Issue- Zone Error

Error : SEVERE ERROR: Zone 'PL.RPTEXP.CREATE_Q.1HZONE01' is defined as type 'mhop' in configuration but also is defined as type '1hop' in meta.db

I got above error in one of EMS server and it prevented EMS to come up properly. EMS used DB as data store. First thing that we should try when we get this kind of error [which indicate a EMS database store corruptions] is to start EMS instance with '-forceStart' command like tibemsd.exe -forceStart. If this does not solve the problem, then we can go to the EMS database and remove the problematic zone records from ZONE_RECS table. In our case due to some reason , ZONE_RECS have more than 100 records for same zone with 1hop or mhop property set  which confused the EMS instance somehow.
