Environment

VCF Operations for Networks 6.14.1

Cause

The application was closing the API response stream prematurely. Because the response was GZIP compressed, the decompression process (GZIPInputStream) attempted to read the remaining data blocks after the connection had already been terminated, resulting in the "Stream closed" exception.

Resolution

This is a known issue impacting VCF Operations for Networks (Formerly Aria Operations for Networks)

Workaround:

If you believe you have encountered this issue, please open a support case with Broadcom Support and refer to this KB article. For more information, see Creating and managing Broadcom support cases.
