I believe this is resolved as of https://go.dev/cl/482195.

mknyszek · 2023-04-05T19:52:50Z

Just to write this down somewhere, it seems like a Linux kernel upgrade was the culprit. The aforementioned CL just pinned the container-optimized OS version we use to the previous LTS release.

I started redeploying at 17:25 EST, so presumably these are old failures that just got picked up.

mknyszek · 2024-10-30T21:04:05Z

This seems related to google/sanitizers#1716, although I'm not sure if the kernel we upgraded to is quite that new.

mknyszek · 2024-10-30T21:06:36Z

Assuming that is the problem, we have a few options to move forward:

Upgrade to a newer version of TSAN for these tests that's compatible with the higher ASLR entropy.
Reduce the number of bits of entropy available to ASLR.
