I'm not familiar with RedHat, but on Debian based systems installing the
"-dev" version of a package will often install unstripped libraries.

Thanks. I tried installing the devel packages as well as manually installing luasocket-2.0.2 from source and still have the same issue. What's strange is that if I run the script manually via the CLI if runs properly.

 

However, the problem is almost certainly in your application, and you've
unhelpfully elided the trace of your code.

I uploaded the full backtrace log to:
