Troubleshooting
Problem
A server "requester" channel pair is unable to allocate a conversation. The configuration provides that only one side of the channel pair defines fully qualified connames (i.e. this is a required parameter for the RQSTR channel) while the remote end (of channel type SVR) uses a blank CONNAME field. On the "requester" channel side, the channel fails to start.
