Comment 2 for bug 1900845

ssync replication completes successfully if I manually (with flag --once) run object replicator on a small handoff partition. rsync works well since I increased timeouts (rsync_timeout, http_timeout, lockup_timeout) but it is incredibly slow. It takes several hours to form list of files for one partition and start actual data transfer.
I am in progress of upgrade from Train/CentOS7 to Ussuri/CentOS8. So I have added one object server (ussuri) and move partitions to it. ssync replication work fine to this ussuri server, but fails with error (IndexError: list index out of range) when replicating from train to train.
