We're seeing this bug consistently (although not consistent per se - the error does not occur immediately after boot, and doesn't immediately disconnect the server from the network; anything from 3 weeks to 3 hours before it starts, and a day or so after is starts before it gets permanently disconnected).
# uname -a
Linux <hostname> 4.15.0-60-generic #67-Ubuntu SMP Thu Aug 22 16:55:30 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz
Ubuntu 18.04.3 LTS
Issue occurred on earlier 18.04 and kernel versions. Server was built as 18.04.1 and is a fairly minimal install acting as a virtual host with KVM/QEMU. It's not heavily loaded and doesn't have a huge amount of traffic. It's a co-located rental so we don't have a detailed spec, but if it's of interest more details are probably available from the provider.
We have other servers with identical hardware from the same provider running 16.04 without any issue.
