Description

The CI checks jobs (both node test and bun test) are crashing with a JavaScript heap out of memory error on all pull requests. All individual tests pass successfully (✓), but the Node.js process runs out of memory after completing the test suite.

This is a separate issue from #17315 (TS2742 in slash.test-harness.ts), and together they block CI from passing on any PR.

Error

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

------ Native stack trace ------
1: 0xe40d24 node::OOMErrorHandler(char const*, v8::OOMDetails const&)
   [/opt/hostedtoolcache/node/22.22.0/x64/bin/node]
2: 0x1216be0 v8::Utils::ReportOOMFailure(...)
3: 0x1216eb7 v8::internal::V8::FatalProcessOutOfMemory(...)

Affected Jobs

• checks (node, test, pnpm canvas:a2ui:bundle && pnpm test) — crashes after all tests pass
• checks (bun, test, pnpm canvas:a2ui:bundle && bunx vitest run --config vitest.unit.config.ts) — same OOM crash

Evidence

Observed on multiple unrelated PRs:

• PR feat: add security-guard extension — agentic safety guardrails #17273: https://github.com/openclaw/openclaw/actions/runs/22039769004/job/63678793395
• PR fix(auth): implement true OAuth flow for Anthropic provider #17320: https://github.com/openclaw/openclaw/actions/runs/22039782039/job/63678821520

All tests show ✓ (pass) before the OOM crash occurs.

Possible Causes

• Node.js heap size may need to be increased via NODE_OPTIONS=--max-old-space-size=4096
• Test suite memory consumption may have grown beyond the default heap limit
• The CI runner (Node 22.22.0 on x64) may need more memory allocation

Impact

High — Combined with #17315, this means no PR can currently pass CI, blocking all contributions.

Suggested Fix

Add NODE_OPTIONS=--max-old-space-size=4096 (or higher) to the test runner CI step, or investigate which test(s) are leaking memory.
