Barrel causing crashes

I am hosting a server for me and some of my friends on my computer. Everything was going well until I started getting multiple crashes in a row. After noticing a set of coordinates in the crash report, I went to the location in-game and found out a barrel was crashing my server. Opening it caused a crash, and destroying it with my axe did as well.

I included the reports of all the crashes that happened to me due to this infamous barrel, as well as a screenshot of the location where it was in-game. In the screenshot, I place a block of cobblestone where the barrel was. The barrel also contained a single carrot, nothing else.
