HTTP/2 is not yet officially supported by OpenResty. It's known that
some Lua APIs provided by ngx_lua may lead to such errors. So be
careful.

While that's true, I've been using it in production with http2 since 1.9.7.* and haven't had any issues that haven't been solved by 1.9.15.1. So I'd love to know how you got it to crash - could you post a more complete configuration to reproduce your chrash?

@agentzh, are there any APIs that are known to be incompatible?

Hi, the same problem as here: https://github.com/openresty/lua-nginx-module/issues/724

switching off lua_check_client_abort fixed that.
