At first, it thought it was the culprit, but it happens without mongo being loaded. One thing, the CLI version seems to be more resilient, it needs more data loaded to crash, whereas with the apache module, it's always crashing. Chromium reports `Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error` when accessing a url. I was able to get a backtrace (with no execute or zbacktrace output) and around frame 30-ish, it specifies entering the shutdown sequence, cleaning up a closure and then the crash. Changing the summary to better reflect the problem. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
