death while spawning in nether makes server unplayable

When entering the nether a skeleton that was fighting me went through, having half a heart of health the skeleton shot me as I spawned in the nether killing me and freezing the entire server. Then i disconnected and it worked fine again except I could no longer join the server until it was manually reset by the server owner. Attached is a screenshot of the error screen upon joining and if you would like I can get a copy of the server logs from the owner.
