I am using Cloudberry explorer and when uploading a large number of files (200 of over 5MB each), the second half of the files uploaded cause many BrokenPipe exceptions in the target server (either via the s3 or swift API). The action that is being interrupted by the client is always a list bucket operation (presumably used in refreshing the cloudberry UI). The operation completes successfully (all files are successfully copied to the S3 target), but it is concerning that the client frequently drops the connection after a certain amount of operations have successfully completed.

Has anyone encountered this? Seems more prevalent on an https connection. Are there any configurations that can mitigate the client connection dropped? Are there any tools that can help diagnose the problem (data wireshark was not helpful).

Thank you for any guidance.
