### Which Issue(s) This PR Fixes Fixes #10052 ### Brief Description addCk() already guards against buffer overflow with popCkMaxBufferSize, but addCkJustOffset() did not have this check. Under high-concurrency POP consumption with large messages, the buffer ConcurrentHashMap could grow without bound, eventually causing OOM in PopBufferMergeService. Fix: Add the same counter > popCkMaxBufferSize guard at the beginning of addCkJustOffset(), consistent with addCk(). ### How Did You Test This Change Existing PopBufferMergeServiceTest (4 tests) all pass. -- This is an automated message from the Apache Git Service.
