The web server process is very sensitive to any bugs. We ran into the exact problem you are having. Our web team was suddenly very unpopular with the other developers. Any bug and the whole app would crash.
We no longer run any code on the web server process on 4D server. Instead we run a client application that acts as a web server. This works pretty well. The code that gets traced is the code on the machine that handled the request. So if you make the request to your web server client application it will trace there. The web server on client can run on the same physical server as your 4D server so long as they aren't both handling requests on the same port. The biggest hurdle we had was getting the correct 4D licensing. There was a special license to make the client run the web server. This may be made more difficult because we are an OEM.

It just quits to the Finder, no error message nothing. I view the trace via screen sharing to the server machine. This is disastrous when other people are using 4D!! Have others run into this? What’s the best way to debug On Web Connection code without crashing the server? Maybe starting the webserver on 4D client? But how does adding a “Trace" On Web Connection code work? Won’t it still trace on the 4D Server?
