Why didn't the agents send data to CMR?

Description

1. Aug 25 ~ Aug 26:
The CMR and agent worked fine after the first installation and configuration.
The data can send to CMR as expected.
2. Aug 27 ~ Aug 31:
CMR server did not receive the data from agents.

3. Sep 1
3.1 Restart CMR. Delete the agent from the CMR agent list. The incident still ocurred.
3.2 Restart the middleware that the agents ran with. CMR and agents work fine.

Question:
1. Why didn't the agent's data transfer to CMR?
2. What should we do if we get the same issue?
3. Need I restart all the middleware that the agent runs with after I restarted CMR?

CMR.logs will upload soon.
