This seems likely to be the same root cause as #59419.

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

Comment From: mknyszek

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.

Comment From: mknyszek

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

Comment From: mknyszek

cos-101-lts is gone now and we were forced to upgrade. These failures are now back.

Comment From: mknyszek

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

Comment From: mknyszek

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.
