QuoteGeneration: Quote generation starts failing after ~4 days of usage #450
Description
We noticed that qgsd stops working after ~4 days of usage. Reproduced on two different machines with Xeon 5 and Xeon 6 with Ubuntu 24.10 where SGX/TDX was set up according to https://github.com/canonical/tdx/. A restart of qgsd resolves the issues.

Workaround: Cronjob to restart qgsd daily. Alternatively, monitor qgsd logs and restart if the error log entry appears.
