## What's changed? close #3903 1. The `org.apache.hertzbeat.collector.timer.TimerDispatcher#goOnline` method will clear all current periodic tasks and temporary tasks. 2. When `ManageServer` receives a `GO_ONLINE` message, it returns an acknowledgment message. If no validation is performed, `Collector` will trigger `goOnline()` again upon receiving the ACK, potentially causing recently established or currently running tasks to be unexpectedly cleared. <img width="1507" height="705" alt="Collector" src="https://github.com/user-attachments/assets/f5470401-9db8-4bda-9f4a-62bf0827a5f6"; /> <img width="1509" height="597" alt="Snipaste_2025-12-15_17-42-37" src="https://github.com/user-attachments/assets/6c8017da-cfb5-49cb-be0d-c6fb32a3766c"; /> Modification details: 1. Blocked ACK messages from triggering `goOnline()`, ensuring the `Collector` only responds to `ManageServer`'s actively issued (REQUEST) online commands. 2.
