Research direction
Start by reproducing the reported memory growth in TiFlash v7.5.6 using a minimal scenario; the issue does not provide reproduction steps or identify files, tests, or an entry point. Compare behavior with v7.1.6 and use the attached memory-usage evidence to determine whether the leak is resolved when usage remains stable.
