SIGABRT in EventQueue::flushEvents / RawEvent destructor on Android (New Architecture, RN 0.86.2) during heavy JS-thread work

Bắt đầu với EventQueue.cpp:113 và RawEvent.h:25, sau đó lần theo luồng scheduling xung quanh qua EventBeat.cpp, RuntimeScheduler_Modern.cpp, JMessageQueueThread.cpp và ReactInstance.cpp. Nếu có thể, hãy tái hiện kịch bản Android foreground-and-import và xác định lý do việc phân phối sự kiện bị hủy; được coi là hoàn tất khi nguyên nhân của lỗi đã được xác định và có một fix đã được kiểm chứng hoặc regression test.

Body

Description

We're seeing a native SIGABRT crash (uncaught, mechanism: signalhandler) with a stack trace entirely inside Fabric/RuntimeScheduler internals — no first-party JS frames involved. It has occurred twice on the same physical device so far.

Environment

• React Native: 0.86.2
• Expo SDK: 57
• Architecture: New Architecture (Fabric) — mandatory on this RN version
• Hermes: yes
• Platform: Android 16
• Device: Samsung Galaxy S24 FE (SM-S721B), arm64-v8a
• App version tag: 1.4.3 (build 40)

Repro context

Both occurrences happened during the same user flow:

1. App resumes from background (onResume).
2. User taps a sync/refresh action, which kicks off a data import: a network download followed by a single large SQLite transaction (expo-sqlite, withExclusiveTransactionAsync) that sequentially imports ~19 groups of records, each step logged synchronously via console.log.
3. A few milliseconds after one of the intermediate import steps logs, the process aborts.

The JS thread is doing sustained synchronous-ish work throughout the import (a tight loop of awaited SQLite operations, several dozen ms apart), right after the app comes back to the foreground — so there may be a backlog of native UI/touch events queued for delivery to JS at the same time.

Notes

• Low frequency so far (2 occurrences on 1 device over 4 days), but 100% of the stack is React Native internals — no app frame to act on from our side.
• Happy to share more Sentry context (breadcrumbs, device info) if useful.
