@alyssawilk ran following command multiple times:

bazel test  -c dbg  //test/integration:tcp_tunneling_integration_test --config=libc++ --test_filter=*IpAndHttpVersions/TcpTunnelingIntegrationTest.UpstreamHttpFiltersPauseAndResume/IPv4_Http3Downstream_HttpUpstreamHttpParserNghttp2NoDeferredProcessingLegacyWithUpstreamHttpFilters* --notest_keep_going --runs_per_test=100 -t-

Not able to get the test failed even once. Can you please review my command once? Also would appreciate any tips on how I can reproduce this.

[alyssawilk]

I'd definitely go up to 2k/4k. it that doesn't get you anywhere you could alwys use the scoped test logger to turn up logging for that test so next it fails CI we have debug info, then you can close it off as "can't repro" :-)

[alyssawilk]

failed again on CI
https://dev.azure.com/cncf/envoy/_build/results?buildId=177371&view=logs&j=1439b9f7-a348-5b50-b5fe-ea612ea91241&t=1002ac43-da84-5fae-70b2-98833b702d09&l=932
so looks like it's repeatable there at least.

this is still happening pretty frequently

oh, will retry
