You need the dbas to help you understand what is happening at the database level.
it would be interesting to see the full error message and stack.
How is the replication implemented?
Is there a script / Java class that is copying the data from Maximo to the replica?
If there is a script/Java class then the error may actually be generated by the replica database in response to the replication process.
The DBAs should be able to get you more information about what is happening e.g. which database tables are growing and where the data is being stored.
