SQL Server 19 UBUNTU - sporadically crashing and restarting

I created a machine with 6 GB of memory, using Ubuntu 20, and installed the latest version of SQL Server Microsoft SQL Server: (RTM-CU8) (KB4577194) - 15.0.4073.23 (X64) Sep 23 2020 16:03:08 Copyright (C) 2019 Microsoft Corporation Express Edition (64-bit) on Linux (Ubuntu 20.04.1 LTS)

Exporadically the system suffers a fatal failure and restarts, taking almost a minute to return. I cannot detect the real reason for the failure and what I could do to resolve it.

I already set the maximum memory limit to 4gb thinking that the system was overflowing the machine's limit. Help me please
