Apache gives an HTTP 500 Error

[Angtagapagligt]

Hello everybody,

we have a software which runs embedded in our ERP software and from an apache server (a web frontend application). Everytime when the user does something very special (can't explain it cause it is completley individual for exact our business [hope you understand what I mean ]) the apache server gives a HTTP 500 error with this informations:

Code: Select all

HTTP Status 500 -

--------------------------------------------------------------------------------

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

I have no idea but I constantly get this error in many web browsers when trying to connect to a certain social network site, and some news sites just as I am about to submit a comment.

Hey,

thanks for your input!

Do you mean just the HTTP Code or the whole message?

If you mean the HTTP Code I could help you (if you don't - just skip this ):
The HTTP status code 500 means a generic error message, given when no more specific message is suitable.

You can find a list with HTTP status codes here:

Many thanks!

Found the following info & link:

" I figured out that my problem was an issue with opening the database. The way I figured it out was to add the following to the servicename.svc.cs file in the InitializeService method:

config.UseVerboseErrors=true;

Thanks to all who tried to help. "

Thanks again but I think this solution is for "Company from Redmond" SQL... Our webserver uses an informix databases (which is already existent cause of another software running on the server which needs it).
Or did I get it wrong?

Thanks!

I actually do a

Code: Select all

cd /
grep "servicename.svc.cs"

The result (so far) is that the cursor is in the next line an nothing else happens... Does the machine still calculate the search or did I use "grep" wrong?

Edit:
Does the command evene make sense? I want grep to search for the string in every single directory (that's why I used "cd /"). Sorry I used grep only with "command | grep "String"" 'till today .

Okay I searched the file now via:

Code: Select all

find / -xdev -type f -print0 | xargs -0 grep -H "servicename.sv.cs"


The command worked but the file doesn't exist (I don't get any results back).
