[CR #554216] When you are using Replication Agent version 15.1 ESD #2 or
earlier to communicate with Replication Server version 15.2 or later, a Replication
Agent query against the RSSD to obtain replication definition information does
not return the appropriate rows, and causes the Replication Agent
to fail with a replication definition not found
error.
Workaround: Set the use_rssd configuration parameter to false to prevent replication definition validation.
