# Subject Collisions

Subscribers to destinations that import from RVCM transports are subject to the same restrictions that direct RVCM listeners. These restrictions are described in the TIBCO Rendezvous documentation, and include subject collisions.

When importing messages from RV, the EMS server creates RVCM listeners using a single name for each transport. This can result in subject collisions if the corresponding EMS subscribers have overlapping topics.
