Following a memcache restart in a SAIO, I've seen the following happen during an object HEAD: - etag_quoter wants to get account/container info to decide whether to quote-wrap or not - account info is a cache miss, so we make a no-auth'ed HEAD to the next filter in the pipeline - eventually this gets down to ratelimit, which *also* wants to get account info - still a cache miss, so we make a *separate* HEAD that eventually talks to the backend and populates cache - ratelimit realizes it can't ratelimit the request and lets the original HEAD through to the backend There's a related bug about how something similar can happen when the backend gets overloaded, but *everything is working* -- we just ought to be talking straight to the proxy app. Note that there's likely something similar going on with container info, but the hardcoded 10% sampling rate makes it harder to see if you're monitoring raw metric streams. I thought I fixed this in the related change, but no :-/ Change-Id: I49447c62abf9375541f396f984c91e128b8a05d5 Related-Change: If9249a42b30e2a2e7c4b0b91f947f24bf891b86f Related-Bug: #1883214 |
