Research direction

Start at ReplaySession.cc:840 in check_ticks_consistency() and inspect the reported SYSCALL: munmap mismatch. Use the record and replay context from the report, including task 7646 and time 45583, to investigate why expected and observed ticks differ. Done means identifying and correcting the cause, but the issue provides no reproduction steps or test location.
