[MM3-users] Internal server errors after upgrade

Hello community,

I'm running the Docker version of MM3. I've just run:

docker-compose stop
docker-compose pull
docker-compose up -d

I am now at versions:

mailman-core:  3.3.4
mailman-web:  2.2.20

I am running a 2-core, 4GB RAM VM on Linode.

The web interface mostly works. However, sometimes/regularly I get a 500 Internal Server Error. In /opt/mailman/core/var/logs/mailman.log I see the errors, but they are usually different. The common thread seems they are always about some sort of database call. Reloading the page is usually successful.

Did anything change with the latest upgrade in terms of database timeouts? Before this upgrade, I was never getting it. (htop does not show anything unusual.)

Any leads?

Thank you, Seth
