Internal Connection fatal error

[Guest]

Hello,

We got this error (Internal connection fatal error) from our application and
at the same we got "server application unavailable" error on the browser. I
looked at the line that was provided by the stack trace and it appeared that
it happened when it tries to connect to the database to fill dataset. What
might cause the database connection to fail or cause this error?

System.Data

Internal connection fatal error.

Is seems as though you are not able to connect to the SQL server. Are you
using SQL security or NTLM in your connection string? Is the web server
behind a filewall on a DMZ? Has this ever worked?

I am unsure of what the code looks like in your InitData method, but I
wonder if you are closing your connection after passing back the reader
object. If you close the connection prior to reading the data, you might
recieve this internal error as well.

Yes, it did work and still working after getting this error, it doesn't
happen on regular basis. It appears to me that it opened the database
connection but it could not execute the datareader. I am not sure about the
filewall, I have to ask the network admin.
