Hiawatha version: Hiawatha v7.4.1, cache, IPv6, URL toolkit
Operating System: linux

I get a CGI timeout error message when executing a long action connection on server side.
1) When time out occur is the request being re-sent?
2) How can I enlarge time out period?
I have tried changing "SessionTimeout" and TimeForCGI, and it didn't help.

THANK YOU

}

1) When a timeout for a CGI script occurs, the CGI is aborted, the issue is logged and a 500 error is sent to the browser.
2) Increasing the run time for a CGI is done via the TimeForCGI setting. This is a (virtual) host specific setting. Don't forget to restart the server after changing this setting.

Hi Hugo
The timeout error isn't shown any more, however I get a "error while executing CGI" and the cgi process is killed.
What does the error mean? How can I debug such case?

Thank you

It means that there's something wrong with your CGI application. What do you see when you run it via the command line? Does the CGI application print the CGI / HTTP headers correctly?

It doesn't happen when I start cgi process, but when I perform certin action on my webpage.
I know something is wrong in my code, I just need help trying to understand it,
It looks like there are 2 approaches to another process in my application, and I thought maybe the timeout caused re-requesting.
Is there a way of getting more information on the cause of the crash?

What programming language are you using? Do you use some sort of CGI or FastCGI library?

I'm using fastCGI
language on server side- C

If you are using any kind of FastCGI library, you should ask there for debugging advice. Otherwise, I guess you're on your own...
