Yes, it seems to cause the issue. Whenever I open a VST plugin, then quit the server and try to start it again it fails. But, when changing the servers NetAddr port to 57111 (just to try a different one) the issue doesn't occur anymore, even when opening and closing VST's. Weird..
I also tried the other way around; after a fresh restart, start server on port 57111, open a VST on it, free it and quit server. Now port 57111 stays open and port 57110 can be used normally (even with VST's). With nmap I can also see it (after quitting the 57111 server):
$ sudo nmap -sU -p57110-57111 127.0.0.1
...
57110/udp closed unknown
57111/udp open|filtered unknown
...
This could provide a workaround to at least be able to work, but something pretty fishy seems to be going on here..
cheers,

Of course I know that this usually means a stray server is around, but Server.killAll doesn't do the trick and there are no scsynth processes around in the activity monitor. The message goes away only after a reboot of the machine. Any ideas what could be going on here? Running macOS 10.14.6 Mojave, tried signed, unsigned and the new big sur build (the latter doesn't give the message, but still says "Server 'localhost' exited with exit code 1."). I do have the VSTPlugin extension installed btw, maybe that is related?
