So we're currently have several experiments in play trying to figure this out: 1. We've got 2x upstream bugfixes applied to our varnishd on cache_misc: https://github.com/varnishcache/varnish-cache/commit/d828a042b3fc2c2b4f1fea83021f0d5508649e50 + https://github.com/varnishcache/varnish-cache/commit/e142a199c53dd9331001cb29678602e726a35690 2. We've removed all of our Content-Length sensitive VCL that was on cache_misc temporarily (basically https://gerrit.wikimedia.org/r/#/c/288231/ , which at one point we partially put back, but then removed again) 3. We've switched from persistent to file storage on the misc backends, manually with puppet disabled. Puppetization to make that semi-permanent if need be: https://gerrit.wikimedia.org/r/288440 (untested) I don't think anyone has reproduced the problem since (3) went live everywhere. So we're in a new state and needing proof that things are still messed up (or not!).
