I can see that inode of the executable and libraries are right for the updated files in the running varnishd via /proc/<pid>/maps (on Linux), I can see that no other varnishd processes are running. I expected that restarting varnish would cause the cache to be wiped and require some period of warmup, however the hit rate held steady at 98% and I don't know why. <div><br></div><div>I'm very happy to be able to do this, its going to make the rest of my upgrades non-disruptive, but I'd like to be able to explain whats happening behind the scenes.
