The Memory Leak Soup Refilled Its Own Bowl
Incident Narrative
A TinyCTO.tv WHAT IF parable about listener leaks, lifecycle cleanup, heap growth. Tie subscriptions to explicit ownership, unsubscribe deterministically, and monitor retained objects by lifecycle.
βThe soup was bottomless because the listeners had no lifecycle.β
π¬Architectural Diagnosis & Root Cause Analysis
Heap grew through dinner service until long GC pauses froze every kitchen station.
Event listeners were registered per order but never unsubscribed when the order lifecycle ended.
Tie subscriptions to explicit ownership, unsubscribe deterministically, and monitor retained objects by lifecycle.
βHEALTH VIOLATION: completed orders remained subscribed to dinnerβ
πParable Script (17 Scenes)
Status: Verified Production DraftOur live order listeners make every table feel remembered!
π¬ Visual: The PM unveils a dining wall where every table has a glowing subscription string.
Table seven paid an hour ago.
π¬ Visual: Fetch points to an empty table whose subscription still pulses.
It still receives soup-status updates.
π¬ Visual: Glitch watches notifications pour into an abandoned bowl.
Who unsubscribes when an order completes?
π¬ Visual: Tiny CTO searches the order lifecycle card for a cleanup step.
Completion is a customer-facing concept.
π¬ Visual: The PM removes cleanup from the internal process poster.
Listener count just passed one hundred thousand.
π¬ Visual: Fetch holds a ticket roll that loops around the kitchen.
Every callback retained the entire order graph.
π¬ Visual: Glitch pulls one callback thread and reveals a complete table memory behind it.
Heap is rising while the dining room empties.
π¬ Visual: Tiny CTO compares empty tables with a climbing memory tank.
Engagement remains excellent after checkout!
π¬ Visual: The PM celebrates post-checkout events sent to empty chairs.
GC pause: six seconds. All stations frozen.
π¬ Visual: Every cook and server rack freezes mid-motion under a giant pause timer.
The soup is updating customers who no longer exist.
π¬ Visual: Glitch serves steaming notification bowls to ghostly empty place settings.
This is not retention. It is a sΓ©ance.
π¬ Visual: Tiny CTO watches old order tickets rise around a candlelit table.
Root cause: per-order listeners with no deterministic teardown.
π¬ Visual: Fetch pins REGISTER and missing UNSUBSCRIBE steps on the lifecycle board.
Can we autoscale memory until closing?
π¬ Visual: The PM wheels in a larger memory cauldron.
Closing is when the process restarts itself!
π¬ Visual: The cauldron overflows and the kitchen power cycles.
Health violation. Bind ownership, unsubscribe on completion, verify retained objects.
π¬ Visual: Fetch cuts expired subscription strings and the heap level drops.
The soup was bottomless because the listeners had no lifecycle.
π¬ Visual: Tiny CTO faces camera as an empty bowl refills itself from an abandoned callback.
