Failed to get peer address

I am trying to run TPCH benchmarks on Comdb2. And calling .execute("DELETE FROM Customer") I encountered the following errors. What should I do to solve this?

Start with the JDBC stack at comdb2.jdbc.SockIO.open (SockIO.java:130), then trace the server messages from accept_thread through read_newsql_query. Reproduce the TPCH DELETE request and compare the client trace with the peer-address and invalid-message errors; done means the failure's cause is identified and the behavior is corrected or clearly documented.
