actix-web hanging after a few hours

[pka]

After a few hours, my actix-web application is hanging. HTTP request are hanging and SIGTERM has no effect. It's serving an iCal document using diesel/MySQL/r2d2 the same way as the diesel/sqlite example. It was only reproducable with Thunderbird as client which differs from a curl request:

curl request:
