Description
Environment
- Version: 5.7.25 OceanBase 4.3.5.3 seekdb (r1.2.0.0)
- Build: 100000172026032022-47f5c...
Description
Memory usage is higher than expected when the system is under idle load (no active queries or minimal workload).
Steps to Reproduce
- Start the OceanBase seekdb instance.
- Ensure no active queries or significant workload are running (idle state).
- Observe the memory usage via monitoring tools or system commands.
- Compare the observed memory usage against expected baseline values for an idle system.
The issue is consistently reproducible (必现).

Research direction
Start by reproducing the idle seekdb instance described in the issue, with no active queries or significant workload. Compare monitoring-tool or system-command measurements with the expected idle baseline; done means the source of the excess memory is identified and the idle usage meets the expected baseline.
