Hi, there is an excessive amount of socket logging from what I believe is the haversine plugin then after some time the x-plane runtime hangs and stops moving, then I have to force quit the app and the logs show this.

0:24:21.676 E/NET: Socket write of 644 bytes returned 64
... lots of this
0:24:21.720 E/NET: Socket write of 456 bytes returned 64
0:24:21.720 E/NET: Socket write of 121 bytes returned 64
0:24:21.720 E/NET: Socket write of 137 bytes returned 64
0:24:21.763 E/NET: Socket write of 33 bytes returned 64
0:24:21.763 E/NET: Socket write of 121 bytes returned 64
0:24:21.763 E/NET: Socket write of --=={This application has crashed because of the plugin: Haversine Air Plugin v5.8}==--
(Art controls are modified.)

my config file; HaversineAir.cfg

#DESTINATION-IP=AUTO
APP-IP=192.168.0.88
#APP-IP=192.168.0.188
#APP-IP=192.168.0.208
#APP-IP=192.168.0.33
#APP-IP=192.168.0.44

I will take the haversine plugin out of the picture and see if it is one of the other plugings that is causing grief

Never seen this before :(

Let me know your findings without the plugin.

Are the log messages from Log.txt or from a macOS log? The AirPlugin doesn't log such messages but could still crash due to some unaccounted network congestion issue I suppose.

This looks like a similar issue:

Maybe it will help?

let me know,
joao @ haversine

would appear that my rendering settings were too high,
not the plugin at all, sorry for casting aspersions,
lets close this ticket.
