There was a problem hiding this comment.
The modified configuration size is very insecure.
Under network fluctuations, rapid RPC timeouts can lead to the following:
- RPC requests fail, and workers quickly lose their jobs.
- Normal business requests fail.
- Frequent job selection/selection issues occur.
