nic-6443 opened a new pull request, #12523: URL: https://github.com/apache/apisix/pull/12523
### Description When using etcd as the config server, the apisix master process performs a full data load during the init phase and saves the result in `loaded_configuration`. After the master forks other worker processes, these worker processes will directly initialize configurations based on `loaded_configuration`: https://github.com/apache/apisix/blob/1b0bb84ccf343bd1aedc4bfff1afa9fcefb7c4d5/apisix/core/config_etcd.lua#L1023-L1031 Since `loaded_configuration` in the master process is not continuously updated, after running for some time, `loaded_configuration` may become outdated. If a worker restarts at this point (e.g., executing `apisix reload` or crash), it will use an outdated configuration for initialization. If any requests are sent to this worker at that time, these requests may be processed by incorrect confiurations. #### Which issue(s) this PR fixes: <!-- *Automatically closes linked issue when PR is merged.
