During the last week, the Linux tsan crashtest task has failed 12 times (= 6 attempts on the same push, higher failure rate if one looks at the attempts) because the worker stopped communicating with taskcluster (e.g. it crashed) - first failure.

Jon, could this be from bug 1715562?

(In reply to Sebastian Hengst [:aryx] (needinfo on intermittent or backout) from comment #0)
It could be. Is it still happening since bug 1716940 landed?

Flags: needinfo?(jcoppeard) → needinfo?(aryx.bugmail)

The issue still affects the latest pushes and backfills indicate it started with bug 1716940.

I can run these tests locally without issue (modulo some TSAN warnings) but they do take a lot of memory (~10GB for the first chunk). I don't think this is directly related to my push (note the previous push also has some failures).

Increasing the chunking fixes the problem on try.

This fixes test crashes suspected to be caused by memory exhaustion.
