[SR-Users] app_lua sr.sqlops.query exit status

Wed Jan 10 13:02:35 CET 2018 

I have master (which should be more or less like latest 5.1) running
with app_lua, but on debian 9.0. From backtrace, no obvious issue.

Wondering if you can get a stripped down version of you config with as
less loaded modules as possible and minimal routing blocks that expose
the issue, so I can try it here. Try to load only the app_lua and the
modules it binds to and see if crashes ... if not, it could be a side
effect from other place.

Cheers,
Daniel
