Yep, that is exactly what we're seeing, glad it's not just us. We're seeing it on a semi-regular basis across six different servers, and when it happens we have no way to remotely reset Hamachi, the 99% CPU load can go for days or weeks until we notice it and/or need remote access.
Really wish LogMeIn would keep the macOS client on par, and as stable as, the Windows version. Hamachi is a great service but we're actively looking for a replacement until this can be resolved.
Thanks,
