SSL I/O error messages

This topic contains error messages that might result due to I/O failures and provides solutions to help you troubleshoot these problems.


The following messages appear due to read failures:

  • SSL0400I: I/O failed, RC <code>.

    • Reason: The server received an error trying to read on the socket.

    • Solution: Some errors are expected during normal processing, especially a '406' error, which you can ignore. If you are unable to access the server and receive these errors, report this problem to Service.

  • :SSL0401E: I/O failed with invalid handle <handle>.

    • Reason: An internal error has occurred.

    • Solution: Report this problem to Service.

  • SSL0402E: I/O failed, the GSKit library is not available.

    • Reason: A call to the GSKit function failed because the dynamic link library unloaded (Windows operating systems only).

    • Solution: Shut down the server and restart.

  • MSSL0403E: I/O failed, internal error.

    • Reason: The communication between client and the server failed due to an error in the GSKit library.

    • Solution: Retry connection from the client. If the error continues, report the problem to Service.

  • SSL0404E: I/O failed, insufficient storage.

    • Reason: The server could not allocate memory needed to complete the operation.

    • Solution: Take action to free up some additional memory. Try reducing the number of threads or processes running, or increasing virtual memory.

  • SSL0405E: I/O failed, SSL handle <handle> is in an invalid state .

    • Reason: The SSL state for the connection is invalid.

    • Solution: Retry connection from the client. If the error continues, report the problem to Service.

  • SSL0406E: I/O failed, cryptography error.

    • Reason: A cryptography error occurred.

    • Solution: None. If the problem continues, report it to Service.

  • SSL0407I: I/O failed, Error validating ASN fields in certificate.

    • Reason: The server was not able to validate one of the ASN fields in the certificate.

    • Solution: Try another certificate.

  • SSL0408E: I/O failed with invalid buffer size. Buffer <address>, size <length>.

    • Reason: The buffer size in the call to the read function is zero or negative.

    • Solution: None. Report this problem to Service.

  • SSL0409I: I/O error occured.

    • Reason: An unexpected network error occurred while reading or writing data over an SSL connection, likely a client disconnecting.

    • Solution: This is an informational message that does not indicate any failure in delivering a response, therefore no solution is provided.

  • SSL0410I: Socket was closed.

    • Reason: An SSL client connection was closed by the client.

    • Solution: This is an informational message that does not indicate any failure in delivering a response, therefore a solution is not provided.

  • SSL0411E: Connection aborted due to unexpected client renegotiation or other malformed SSL record <errorcode>.

    • Reason: An unexpected client renegotiation has been detected or an incorrectly formatted SSL message has been received. Thus, the SSL connection has been stopped.

    • Solution: Check the client settings and retry connection between the client and the server.
