When two clients connect to ocserv at the same time, the later one connecting to the server fails to get its IPv6 address allocation. When one of the client disconnects from the ocserv server, the kernel crashes.

Sorry for the delay in replying. The issue has been reported upstream.
Thanks for reporting!
The problem can be addressed earlier if you provide upstream more information.
Can you reproduce the issue on FreeBSD 12.0-RELEASE?
Sorry for the delay. Seems like FreeBSD 12.0-RELEASE is not affected by this issue.

Oops, 12.0-RELEASE is also affected by this issue. I am going to upload the dmesg soon.

Would you mind trying again with ocserv 0.12.2?
The problem is also reproducible after upgrading ocserv to 0.12.2
