Why is the worker/tasks.db file so large on the traefik controller node?

We have a 1x Controller and 2x Proxy setup running TraefikEE 2.5.0. There is a file on the controller at /opt/traefikee/data/host-name/worker/tasks.db that is 2.1GB. Should that file be that large, and is there any way to reduce it? It's by no means a critical issue, I just want to keep the footprint of the server small.
