This internal error reflects a failure in communication between your application and the network software (Informix STAR, IBM Informix NET, IBM Informix NET for Windows, and so on) at another site. Restart your application. Look for operating-system messages that might give more information.
If you are using IBM Informix NET for Windows, a Windows Sockets problem might exist; check your Windows Sockets 1.1 documentation for more information. Check the sqlerrm field of the sqlca structure for the particular Windows Sockets message.
In the ASCL context, this error might also indicate problems in your informix.ini file. Verify that the SERVICE, HOST, and PASSWD entries are correct.
If the problem recurs, ask your network administrator to run network diagnostics. If the error recurs, note all circumstances and contact IBM Informix Technical Support.
