PDF Export never finishes for a document, Weasyprint service seems to crash, Docker container restart is necessary

[nweidemann]

Current Behavior

PDF Export never finishes for a specific document (but we are not able to share this),
Regular documents from DrivePilot Example do work without problems.

Weasyprint service seems to crash, the about page of PDF Exporter is not available after the try of this export.
It is available again, after docker container is stopped (and started again).

When trying to export this page again, after cancellation of the 1st export a error regarding Weasyprint is shown (status 500)

Please see the output of _docker logs weasyprint-service

Any clues what could be wrong?
