This internal error reflects a failure in communications between your application and the database server on the other computer system. Check that all software components are at compatible software levels. Recompile and relink your application program if necessary. If the problem recurs, note all circumstances and contact IBM Informix Technical Support.
For a Windows system, check your Client Installation and Configuration Guide for information about using Setnet32 to set the environment variables that affect client-server communications.
For versions prior to Version 6.0, see the appropriate IBM Informix NET/Informix STAR Installation and Configuration Guide for a compatibility chart.
