Thread:Project:Support desk/Server hangs up while using bot class/reply (7)

I don't know anything from the script you linked, and I'm not sure if I understand correctly your issue.

You say the server hangs. Could you please specify? The entire server (operating system) freezes? Just the web service (apache?). I doubt any of both issues could happen, and if they happen there must be something wrong with the web service and not MediaWiki.

If it's the script that you run what hangs, then you could look in the server access logs to see if the request even arrives to the server. If not it may be a firewall issue or some other interference.
