mssql_execute(): stored procedure execution failed

Hi,

I've migrated a linux server

    * from: freetds-0.61-1
    * to: freetds-bin 0.82-6

Now we experience problem with stored procedure, called that way from 
php (its legacy code)

$query=mssql_init("mail_exclusion_get", $conn);
mssql_bind($query, "@id", $receiverId, SQLINT4);
mssql_bind($query, "@type", $tag_mail, SQLINT4);
$rt=mssql_execute($query);
mssql_free_statement($query);


sometime it works, sometime not.

Activating freetds log doesn't seem to give useful information.

We patched some procedure call with :

mssql_query("EXEC mail_exclusion_get @id = 1276963, @type = 1");

To you have any clue to fix this problem?

Regards,
Sylvain.
