When running in serve mode, the log will contain two session IDs. #1649

When I create two sessions at the same time, the "session" tag in the log of the first session will be overwritten by the second session.
As shown in the picture, the first session ID is a_7c60d2e10c7c4e09a2d1302fc8294b4b, and the second session ID is a_2775284346704b2a8ef42a0f9f2d4623.

It is because log.clone() will get the same logger from cached

The clone function should return a new logger
