Bedrock Server (Ubuntu) crash on Village::getBedPOICount

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.

_________________________________________

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.

Same issue as BDS-11039 (reported before I saw this issue)
