Comment 21 for bug 1161599

So testing with both of my merge proposals, I will still occasionally see a '400 Bad Request' error or some other error such as a socket error or a '502 Bad Gateway'. Most of the time, the retry is successful, but on a rare occasion, I'm seeing all 5 retries fail which causes the backup to fail. I've attached a file with a snippet of the debug output of a failed backup.

This is very strange and I have no clue why the Apache server is responding in these ways. I guess this still needs more investigation.
