1.10.2 TPS Locking up when mounting a dragon

[Sora-Canstavia]

Hey, I Don't know if this has been reported before, or even if it is 100% for sure dragon mounts, but it always seems to coincide with someone getting on a dragon, and the logs support this.
So, on occasion when someone on my server right clicks their tamed dragon to mount it sometimes, not all the time, but sometimes the TPS will suddenly drop to 1TPS for about half a minute and then return to normal, when I Check the servers activity (it's a dedicated, home-run server, I Can provide machine specs if that's helpful at all) but the CPU usage skyrockets to 100% usage while this is going on and checking the logs, while the CPU is maxxed out (only on one core at a time, the version of linux I Am running shuffles the process across cores if one is overloaded) the logs say this at this time:

the TPS and CPU return to normal after the last line, which leads me to believe it is dragon mounts. If I Am mistaken, then I Apologize in advance.
