DMCC uses TSAPI for Routing. Therefore, you may be able to learn more from the TSAPI traces on the AE Services. In particular, I don't think I have come across the performanceLimitExceeded error before. This error will have been generated from a TSAPI error. The TSAPI error may be easier to decypher.
There are instructions for enabling TSAPI traces in the devconnect FAQ "What is the procedure for enabling and accessing the AE Services logs for TSAPI (trace, tracing, g3trace, csta_trace)?". The csta trace file will show the communication between the DMCC & TSAPI systems. The g3 traces will show the messages to/from the Communication Manager. These may give you a clearer picture of what is happening.
You should be able to get a clue as to the meaning of the error from the document "TSAPI for Avaya Communication Manager Programmer's Reference".
