How to track down a 500 error - Apache Web Server

571 Contributor

I have 3 web servers (one production and two test).

Production machine runs Apache 2.0.54
Old test machine runs Apache 2.0.44
New test machine runs Apache 2.0.54

In one of my apps I make an ajax call (only one of several others work fine). I get this error message

Expand|Select|Wrap|Line Numbers

 
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<html><head>

<title>500 Internal Server Error</title>

</head><body>

<h1>Internal Server Error</h1>

<p>The server encountered an internal error or

misconfiguration and was unable to complete

your request.</p>

Furthermore the error log records this message

 [Mon Sep 22 07:22:54 2008] [error] [client 200.1.2.167] Premature end of script headers: GetData.exe, referer: http://200.1.2.167/.../Job.exe
 
 

The problem occurs in my javaScript file where it is trying to send the query string on the ajax call.

Expand|Select|Wrap|Line Numbers

xmlHttp.send(queryString);

That of course is the application calling the "GetData.ex e" app

This code/app is the identical code running on all 3 machines. The code works fine on the Old test machine and the Production machine. I only get the error on the New test machine. So I am not really suspecting the code to be the problem as much as how I setup the Apache server.

My problem is this I just don't know where to look in my config file or anywhere else for that matter to try to fix this problem.

Any suggestions on how I might begin to tackle this problem would be appreciated.

Well it appears it was my ODBC connector to MySQL that created the problem. I have two versions of MySQL odbc connectors both in the 3.51 series but different builds. The newer version had so language format options the older did not. As I do not understand to much about that I reverted to the older connector where life is simpler.

Help needed to track down a PHP error

by: JDJones | last post by:

A friend just changed servers with her web site. The new server uses PHP 4.3.2 as opposed to the old server that had one of the 4.0.x's (don't remember exactly which one). Now I know all about the register globals change but one of the pages is suddenly throwing me an error I can't figure out. It is not on a form. It is a script to include a random quote on a page once every 50 page loads. It worked fine on the old server but is throwing...

Morning all. We have an ASP.net (1.1) app that is causing an error that sends us an email.

Most Interesting Bug Track Down

by: Frederick Gotham | last post by:

I thought it might be interesting to share experiences of tracking down a subtle or mysterious bug. I myself haven't much experience with tracking down bugs, but there's one in particular which comes to mind. I was writing usable which dealt with strings. As per usual with my code, I made it efficient to the extreme. One thing I did was replace, where possible, any usages of "strlen" with something like: struct PtrAndLen { char *p;
