Forum OpenACS Development: Re: Calls to server itself are ok on command line, but hang in /ds/shell

turn on verbosity and tracing in the curl call, and redirect the stdout+stderr to some debug file. curl should tell you, what's going on. as brian said, dns is an option, but as well a firewall or configuration issues like small-dimensioned special purpose connection pools.
Thanks, I will try your suggestions.

This must be something specific to nsd/nginx in that particular environment, because curl on the very same server works as expected, using exactly the same command in bash as in /ds/shell, except for the "exec" part of course.
