Actual Behavior

I believe that the Ai updates in 1.7.0 are causing a severe lag that is causing my server to crash.
I profiled the server during one of these hangs and it seams to me that the animania ai functions are eating up cpu resources.

I created a flight recording on my server with jmx in the jdk so you can take a look.

Steps to Reproduce

move around an area with a lot of animals. It seem to happen when looking at trees a lot.

I am running the mod pack
dungeons dragons and space shuttles 6.0b

MC 1.12.2
animania 1.7.2
server
Crash log

@mindcloud69 You're correct that the server crashed because the watchdog detected a high amount of lag. Your log mentions this crash report: /minecraft/dnd/./crash-reports/crash-2019-09-29_22.04.40-server.txt - Would you be able to upload that file to github/pastebin etc so that we can see more diagnostic information? What would also be helpful would be if you could do /forge entity list when things are feeling laggy, and then upload your /logs/latest.log from the server, so we can have a look at what animals are currently active.

Finally, I personally am not sure how to open your jmx file, but if you use a server profiling tool like the ones on this page (I recommend Spark as it's the easiest to use), it will give you more granular info on what in your world is taking up the most resources.

I am sorry I have been busy with IRL responsibilities. I will attempt to get you the requested logs soon. The profiling tool I used comes with the Oracle JDK. You can find the JMX executable in you jdk bin dir. Then it is just a matter of file and open if you want to look at it.

edit: I just double checked, the executable is jmc or jmc.exe in windows "java mission control"

Since this was on version 1.7.0 and many performance improvements have happened since then, I will consider this one as fixed and close it.
