We ran into the exact same issue with pg_dump after upgrading to Bionic (4.15.0-1023-aws kernel) on r5.xlarge (a next-gen Nitro instance). After 16-80 MB of data is received, tcpdump shows the receive window collapsing to 1 (not quite suddenly, but quickly), and it never recovers. We have engaged with AWS support on this issue, and they referred us to this bug.
Other than downgrading the kernel, has anyone discovered any other workarounds? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1796469 Title: aws s3 cp --recursive hangs on the last file on a large file transfer to instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-aws/+bug/1796469/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
