This internal error reflects a failure in communication between your application, Informix STAR or IBM Informix NET software, and the database server on the other computer system. Check that all three of these software components are at compatible software levels. (For versions prior to Version 6.0, see the appropriate IBM Informix NET/Informix STAR Installation and Configuration Guide for a compatibility chart). Recompile and relink your application program if necessary. If the problem recurs, note all circumstances and contact IBM Informix Technical Support.
