We are using Chroma to build a project. The service is deployed on a Linux system. Initially, the service ran without any issues. However, after we increased the scale of the database, problems began to occur. The service now frequently crashes with the same error (the detailed traceback is attached). The current situation is that the service can start normally, but after some time (erratically), it crashes.

We have Googled and found some solutions, but they still do not work：

1. We changed the relative database file path to the absolute ones.
2. We used print() to ensure that the database connection can be closed.
3. We used multi-process to request the main service, but in the test, we did NOT receive the same error.
