If fixing this require some time, could we disable this test first? @nezdolik

There is another type of flake in asan that needs fixing:

@nezdolik not sure if its the same issue but im seeing this fail asan quite a bit (in other testing repo) - and its failed postsubmit here

https://dev.azure.com/cncf/envoy/_build/results?buildId=179259&view=logs&j=1439b9f7-a348-5b50-b5fe-ea612ea91241&t=1002ac43-da84-5fae-70b2-98833b702d09&l=282

possibly unrelated but ive also seen this fail tsan a few times

@phlax yup asan still needs addressing. Did not notice that issue got closed. Did you see tsan failures after 27th August?

phlax commented Sep 5, 2024

yeah saw tsan issues yesterday, altho seemed to go away after rerunning - probably relevant is that the workers it was running on are pretty resource-constrained

so, im doing a load of testing that are non-cached, and im seeing this quite a bit in compile-time-options also

which i think doesnt fail anything - so may be expected/related to test - but also wondering if its related to issues seen elsewhere

contrary to what i said above it does fail the CI

also on uncached runs it seems ~50/50 whether this passes

@nezdolik i think this issue is pretty high priority given the frequency this is failing stuff, and the nature of what is failing

I'm seeing this failure today in #35698: https://dev.azure.com/cncf/envoy/_build/results?buildId=179725&view=logs&j=76424b50-4542-51d2-ddfa-1b282263c744&t=ee414bb6-1c71-528f-760c-893708054276 -- are we sure this is fixed?

should have probably created 3 separate issues per each ci failure. So far tsan and asan checks have been fixed. Now there is one more on release tests (not related to tsan or asan):
