Big problem with plugin on 4D Server

[Stefan Hanshans]

I have a plugin that communicates with an external application via  
TCP/IP on Windows. This plugin has to run on a 4D Server in a  
separate process. If the external App is not responding, 4D Server is  
blocked a few ticks and loses connection to the network. The client  
then get error -10001.

How can I avoid that the server is blocked? Can I create a separate  
task or something else?

TIA

You could use a non-blocking socket.

Yes, another option is to handle the communication in a separate thread.

We took the third option and are now using a separate client to talk  
to the external application. In Or case this is much better than  
executing the plugin on the server.
