poorbarcode opened a new pull request, #25805:
URL: https://github.com/apache/pulsar/pull/25805
### Motivation
| Time/Threads | `consumer.receiveMessage` | Close Pulsar Source | Receive
messages from Server |
| --- | --- | --- | --- |
| 1 | | | push a message into `consumer.incomingMessages` |
| 2 | pop a message from `consumer.incomingMessages` |
| 3 | reduce `incomingMessagesSize`: `0 -> -45` |
| 4 | | Close Pulsar Source |
| 5 | | Close producer |
| 6 | | Failed due to `Try to reserve/release memory failed, the param
memorySize is a negative value` |
| 7 | | | plus `consumer.incomingMessagesSize` |
### Modifications
- Let increasing `incomingMessagesSize` and decreasing
`incomingMessagesSize` run in the same thread
- Since it is hard to add a test to reproduce the issue, I skipped to
write the test
- Improve logs
