I have the same crash log, if you press on "view Raw" probably you will see "***** OUT OF MEMORY! attempted allocation size: 1048718 ****" like me, but I dont see something related to a sourcemod plugin on the thread crashed.
So I created a plugin for dump sourcemod handles during the time and keep the latest dump log before the crash and also log all the new entities created for see if is something related to the map.
I attach the plugin, tell me if you found something, I decided to made it today so I will say too if I found something. The dump handles log will appear on csgo/ directory and the entities created will appear on addons/sourcemod/logs
Btw, for discard some command you have my other plugin too -> https://forums.alliedmods.net/showthread.php?p=2386655
