[BDS-10926] Bedrock Server (Ubuntu) crash on Village::getBedPOICount

Steps to reproduce:

Download world at https://drive.google.com/file/d/17cezewkfLQDhh9zkjxpr6vBb2TCgn_FM/view?usp=sharing and extract it
Set it up to be served by a vanilla install of Bedrock server (Ubuntu) v1.16.201, all default settings
Join the server from a Win10 client v1.16.201
Teleport to coordinates 438, 63, 84 (or walk east from the world spawn to reach that point)
Stand there doing nothing for about 20 seconds

Result:

Server crashes with the following message in the console:

Using the same world file on a Windows bedrock server works fine. Only the Ubuntu server seems to crash.

I have the same issue, using dedicated Bedrock server on Linux, all players report getting disconnected after several minutes of playing, and the server console shows the same error. Seems to occur when invoking the Village:getBedPOICount function. This started earlier this week when the server was on version 1.16.200 – today I tried updating the server to 1.16.201.2 and the issue still persists.

UPDATE: 01/10/2021 - Purchased server from hosting service and installed world with same result.

_________________________________________

I'm experiencing the same issue. I've been running the server in a TrueNAS VM for more than a year with no issue until now.

VM Specifications:

TrueNAS 12.0 U1

Ubuntu Server 20.4.1

2GB RAM

Up to 3 threads dedicated of Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz

The problem seems to have began with the MC update to 1.16.200 and persists through 1.16.201

Below is my error log:

This is the same as (or very similar to) BDS-10777.
