Public bug reported: See here for all details: https://answers.launchpad.net/ubuntu/+source/ocserv/+question/700616 It does only occur on arm64 (Raspberry Pi), but not on amd64.
I don't think that this is a bug in ocserv, I assume it is in libev4. I tried to set up a ocserv VPN server. When I try to establish the connection, I get the following message, repeatedly. The tunnel can't be established.
