Earlier builds (e.g. https://ci.nodejs.org/job/node-test-commit-ibmi/466/) are passing -- the source change between the last passing build and the failing builds is https://github.com/nodejs/node/commit/c61870c376e2f5b0dbaa939972c46745e21cdbdd (the libuv 1.42.0 update). For the record, the libuv builds (libuv-test-commit-ibmi and libuv-test-commit-ibmi-cmake) have been passing.

Both the failing builds were on test-iinthecloud-ibmi73-ppc64_be-1. I've started a new build (in progress) on test-iinthecloud-ibmi73-ppc64_be-2 to check whether it's host specific: https://ci.nodejs.org/job/node-test-commit-ibmi/469/nodes=ibmi73-ppc64/

Research direction

Start by comparing the passing IBM i build 466 with failing builds 467 and 468, then inspect commit c61870c376e2f5b0dbaa939972c46745e21cdbdd, the libuv 1.42.0 update. Re-run the listed parallel HTTP/TLS tests and pummel/test-regress-GH-892.js on both IBM i hosts, using build 469 to check whether the failure is host-specific. Done means the regression is explained and the affected IBM i tests pass again.
