Bug Report: Slave's accessMessageInMemoryMaxRatio becomes negative Environment - OS: CentOS 6.9 - RocketMQ version: 5.3.1 (branch/tag: develop) - JDK Version: 1.8.0_202 Description The slave's `accessMessageInMemoryMaxRatio` parameter may become negative in certain scenarios, causing the consumer to consistently consume from the slave when it shouldn't. Steps to Reproduce 1. Deploy one master and one slave configuration 2. Update slave config (excluding `accessMessageInMemoryMaxRatio`) 3. Restart the slave 4. Repeat steps 2-3 in a loop After several iterations, the `accessMessageInMemoryMaxRatio` becomes negative. Expected Behavior The `accessMessageInMemoryMaxRatio` should maintain its default value of 30 (or whatever configured value was set). Actual Behavior The value changes to 20 and eventually becomes negative. Additional Context This issue appears during configuration updates and restarts of the slave node. The negative value causes improper consumer behavior where messages are always consumed from the slave. Possible Impact - Consumers may get incorrect message ordering - System may experience performance degradation - Slave node might be overloaded with read requests Some suggestions to improve your bug report: 1. Add more specific details about the configuration changes you're making in step 2 2. Include any relevant logs or error messages you've observed 3. Specify how many iterations are typically needed to reproduce the issue 4. If possible, include information about whether this affects message persistence or just consumption 5. Consider adding whether this happens with specific topic/queue configurations -- This is an automated message from the Apache Git Service.
