Closed as not planned

Description

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1574051
Build error leg or test failing: maccatalyst-arm64 Release AllSubsets_CoreCLR_RuntimeTests - CoreCLR runtime test work items (CoreMangLib, GC, jit64_3, Loader, Methodical_, Regression_) hang and are killed at the 3-hour Helix timeout (exit code 70)

KBE authoring guidance (ci-failure-scan)
  • Error Details is for readers. Paste the full exception, stack trace, or build error excerpt so the failure is understandable without opening the raw log.
  • Build Analysis parses only the single JSON block under Error Message.
  • ErrorMessage is a case-sensitive ordinal String.Contains substring copied verbatim from the failing log.
  • Set BuildRetry to true only for a clear infrastructure retry case. ExcludeConsoleLog disables Helix console-log scanning.

Error Details

On runtime-extra-platforms (definition 154, required gate), every CoreCLR runtime-test work item on the maccatalyst-arm64 Release AllSubsets_CoreCLR_RuntimeTests leg hangs and is force-killed when the Helix work item reaches its 3-hour (10800 second) execution limit, reporting exit code 70. The same leg fails in this manner across multiple consecutive builds (e.g. 1567845, 1569716, source 1574051, follow-up 1574376), taking down CoreMangLib, GC, jit64_3, Loader, Methodical_d1/do/ro, Regression_7 and other work items in the leg.
