Comment (by pege):

 I did some tests, the issue is easiest to reproduce by receiving bulk
 data. Since there is an SSH server behind the onion service I used for
 testing, I went with `ssh -vvv eve.arbitrary.onion 'cat /dev/urandom'
 >/dev/null`.

 Here is some of the SSH debug output for some of the test runs:

 I did about 50 more runs, "received" never exceeded 512KiB. Could be a
 coincident though.
