Github user zwoop commented on the issue: https://github.com/apache/trafficserver/pull/1488 I see now, there's a new configuration, proxy.config.ssl.server.multicert.exit_on_load_fail, which would exit on load errors. Surprised that this is not the default to "1" though. However, the fix above would retain (what I think is) correct behavior on reloads, and if proxy.config.ssl.server.multicert.exit_on_load_fail is off (0), you'd still be able to load the initially broken configuration. Why anyone wants a broken configuration is beyond me, but I'm ok with this, but think it should be changed to "1" for v8.0.0.
