Thanks for that. Though for the record, I am not seeing any difference since your changes.
I too have seen it working fine, just as you showed in your screenshot. But only after the 'core eventually connects without the SOS and reboot loop. In 99 out of 100 occasions (guessing) my 'core will not connect the first time. Once it finally does, like @pixelboy, if I reset the 'core, then we’re back to SOS/reboot for about 3 minutes 50 seconds, before my 'core finally connects without the SOS. From that point, all appears well and good, until the next disconnection – whether than be by reset or any other means, like shutting down the server or severing the network connection.
As reported elsewhere, each time the SOS/reboot occurs, the server actually reports that a valid handshake occurred and that the connection completed successfully. Then of course, that ‘valid’ connection ID times out, because the 'core crashed. I assume this is what @pixelboy is seeing, also.
It’s very interesting that this problem occurs persistently with just Tinker for me, while for @kennethlimcp and and another (I think?) it seems to only be with user firmware.
FWIW, is @pixelboy running 64-bit Linux?
