Minecraft Java Edition version 1.14
The server computer is running Mac OS X 10.11.6
The server is running Java Version 8 Update 211 (build 1.8.0_211-b12)

I installed version 1.14 a couple hours ago.
When I play using my op account and I kill a mob with any weapon the server locks up for a minute or more. Sometimes it recovers and continues, but about 70% of the time it disconnects the users with a "server timed out" message. So far I have one time that the server log shows the server software shut down the server.

But when I play on the same server, same version (1.14) using my non-op account (from the same client computer) everything works perfectly.
The server startup script says:
#!/bin/bash
cd "$(dirname "$0")"
exec java -Xmx2G -Xms2G -jar minecraft_server.1.14.0.jar nogui
.... which shows that the server is getting 2GB of memory to use.
========== update ========== 25 April 2019
Further testing reveals that if I use minecraft account #1 to deop account #2 ... and then re-op account #2 ... then the problem of account #2 causing a freeze has been eliminated.
Additionally, I have a third account that has op privileges on the server and after re-op'ing account #2 ... now account #3 (that was never deop'ed) no longer has the problem.
Summary: it appears that if just one op account gets deop'ed and the re-op'ed the problem for ALL op accounts is solved.
