ranxuxin001 opened a new issue, #9528:
URL: https://github.com/apache/apisix/issues/9528
### Current Behavior
apisix 3.3 runs with etcd v3.5. It generates core dump at night. It seems
connection to etcd has problem. Then grpc library generates error response
structure. It uses the field which is nil in this structure at that time.
### Expected Behavior
_No response_
### Error Logs
panic: runtime error: invalid memory address or nil pointer dereference
