The log above doesn't load for me... Is there a more recent example of the problem? With no other info to go on, I'm not sure this will be actionable.

I'm also not familiar with where symbolization is configured and who owns such configs. Does it belong to Infra>Client>Chrome? +jbudorick - maybe you know?

#1: we've done symbolization work elsewhere. I'd lean toward us owning it.

That logdog doesn't have that when it's only from two months ago is a little concerning...

As for a more recent example: perhaps https://logs.chromium.org/v/?s=chromium%2Fbb%2Ftryserver.chromium.linux%2Flinux_chromium_asan_rel_ng%2F521696%2F%2B%2Frecipes%2Fsteps%2Fbrowser_tests__with_patch_%2F0%2Flogs%2FCaptivePortalBrowserTest.InterstitialTimerCertErrorAfterSlowLoad%2F0 ?
