The current malloc_conf only sets retain:false, which prevents jemalloc from retaining virtual memory but does not actively purge dirty/muzzy pages. On long-running EasyTier nodes this can lead to inflated RSS because freed arena pages are not returned to the OS promptly. This tunes the jemalloc decay parameters: background_thread:true — enables background GC threads so purge happens without blocking allocation hot paths. dirty_decay_ms:1000 / muzzy_decay_ms:1000 — return unused pages to the OS within ~1s instead of holding them indefinitely.
