Title: Exception occurred at address 058AB434
Post by: Matthew on October 30, 2013, 04:35:56 AM

Hello.

My NetTalk: 7.10
My Clarion: 8

I have following problem:

1. My webpage is based on frames (top frame - header. left frame - menu, bottom frame - footer, middle frame - data).
2. After Clicking menu option in the left frame it open webpage in the middle frame.
3. So when I start clicking really fast for testing (for example in firefox) after some time:
        - web server stopped responding and website is hanging up
          or
        - web server give following exception:

Exception occurred at address 058AB434

Could anyone help?

Why webpage is hanging up when there is no exception?

Why there is exception sometimes which close the web server?

It seems that this exception applies to functions: SIMPLECLOSESOCKET

Matthew

I upgraded NetTalk to version 7.28 and problem is still the same.

But:
I discovered that if I run webserver on the other machine and I browse my website in firefox from another machine then probably there is no exception and website works fine (at least in my situation).

So I don't know why such a problem occurs when I run webserver and webbrowser on the same machine.

Matthew
