If you try to upload a file with a HTML form any MySQL-Link gets lost.
Example:
<?php
$conn=mysql_connect(HOST,USER,PASSWORD);
$db=mysql_select_db(DBNAME,$conn);
mysql_query("select max(id) from TABLE",$db);
?>
<html>
  <form enctype="multipart/form-data"  method="POST">
  <input type="file" name="uploadfile">
  <input type="submit">
  <form>
</html> 

If you choose a file this error occurs: Warning: 1 is not a MySQL link index in FILENAME on line 4
Without choosing a file everthing is OK.

I can't say anything about the configuration because I'm only consumer of vservers.com, but you
may look at http://www.vskm.org/errors/phpinfo.php3 where you can see the output of the 
phpinfo() function.

Same error occurs in PHP Version 3.0.7 which is part of
the SuSE Linux 6.1 distribution.

It's the same problem with msql.

What do you mean by it getting lost?

Are you submitting a file upload to a PHP page that has
a MySQL link opened in it?  Does it not open?  Does it open
and then suddenly close?

I'm not sure if the example you enclosed represents a single file (in which case it's a really weird script) or two files, in which case I don't understand when the SQL handle may get lost...

In the snippet provided, you are not providing
the mysql_query() function with a link identifier, as
described in the manual.

Try:

mysql_query("select max(id) from TABLE",$conn);
                                        ^^^^^
Same goes for msql.
