Odroid sync problem - version 2.6.3

[Tim77]

Sync is failing on my new Odroid N2, running resilio-sync_2.6.3-1_arm64.deb on Ubuntu 18.04.

History: For years I've run sync on a Raspberry Pi, with just the occasional hiccough. My setup is that the synced folders all exist on a BSD machine that shares them with the Pi via samba. Unfortunately, network speed on the Pi is too slow, so I upgraded to an Odroid N2 with the same samba sharing configuration. I followed the instructions here: https://help.resilio.com/hc/en-us/articles/206178924-Installing-Sync-package-on-Linux. Sync is running under the rslsync account and I've made sure that this account has all rights on the shared folders.

Here's what happens: I can add all my folders to the sync identity on the Odroid and they all index successfully. The problem starts when I share these folders with other devices. The first few shares seem to go OK, but as I add more devices, I noticed in the logs that sync would finish syncing up that device and then go into a crazy loop would where it would basically initialize itself over and over. After many cycles of this it would seem to stabilize. However, when I added the last few of my devices. It would not stop looping and now consistently dies with these final entries in the log:

When this dies, you can see that the sync process is still there:
odroid@odroid:~$ ps aux|grep resilio
rslsync   5282  0.0  0.1 172256  6592 ?        Ssl  May06   0:00 /usr/bin/rslsync --config /etc/resilio-sync/config.json
odroid    7847  0.0  0.0   2704   644 pts/0    S+   16:17   0:00 grep --color=auto resilio
odroid@odroid:~$

But it doesn't respond to systemctl stop and the only way to shut it down is to kill -9. I tried tearing it all down and starting over and the same thing happens.

Does this help? I'm seeing it repeatedly in the log:

I've verified that outgoing ports 4000, 3000, and 3001 are open.

I tried starting over using version 2.6.2-1 instead. So far, this is looking stable, but i haven't pushed it that hard yet.

Version 2.6.2-1 is working with this system, so I'm staying with it.

There does seem to be a problem with 2.6.3-1. For the record, this is:
Odroid N2
Ubuntu 18.04.2 LTS (GNU/Linux 4.9.170-27 aarch64)
