执行mssql_query函数时，简单的PHP脚本将停止执行且没有错误

Question

I have this simple PHP script, which is calling a MSSQL db procedure:

<?php

ini_set('display_errors', 1);
error_reporting(E_ALL);

mssql_connect('server', 'user', 'pass');
mssql_select_db('dbname');

if(mssql_query(' exec dbo.SomeProcedure '))
    echo "OK\n";
else
    echo "FAIL\n";

When trying to call the script from web browser, I receive a "connection reset" message. When trying to call it from command line, no echo command is executed. It just fails on line with mssql_query call.

No error message is displayed, or saved to php error log (defined in virtualhost). The strange thing is, that if I call another procedure within the same PHP script, it works fine. And if I call the same procedure (under the same user) directly in database, it also works fine (no error raised).

No additional error handling is implemented, the mentioned piece of code is the whole content of my script.

Can someone, please, give me a advice, how to debug/find out, what is gone wrong?

PHP version : PHP 5.3.3-7+squeeze25 with Suhosin-Patch (cli)
MSSQL driver : freetds

It just fails on line with mssql_query call.

This means either error is before if or i the call .

I receive a "connection reset" message.

Probably means that there is an error in connection like database name or pass, etc . So make sure the parameters in connection establishing line are correct
