# Scanner: deliverWebhook goroutines use blocking time.Sleep — goroutine leak under sustained failure
|
|
|
|
**Severity:** medium
|
|
**Domain:** Scanner
|
|
**Labels:** bug, scanner, goroutine-leak
|
|
|
|
## Description
|
|
|
|
`scanner/webhook.go:90` spawns a goroutine per webhook delivery that uses `time.Sleep` for retry backoff. Under sustained backend failure, many goroutines accumulate blocking on sleep with no upper bound on their count or total memory usage.
|
|
|
|
## Options
|
|
|
|
1. Replace per-delivery sleeping goroutines with a persisted retry queue + ticker (already partially present).
|
|
2. Use a bounded worker pool + context cancellation instead of `time.Sleep`.
|
|
3. Cap concurrent in-flight deliveries with a semaphore.
|
|
|
|
## Recommendation
|
|
|
|
Move retries to the persisted queue/ticker model with a bounded worker pool and context-aware delays. Coordinate with ISSUE-112.
