Here is the scoop:

We are experiencing problems with PHP, Apache, freeTDS, RH6.1, and MSSQL
6.5(NT4). We are able to connect, make SELECT queries, etc. Everything works
great. The problem happens when we execute an INSERT, or an UPDATE query. The
database on the remote system is updated correctly. However, the script
segfaults, and never returns. This happens when using normal connects or
persistent. I have attached a small script which exhibits this behaviour, and
the TDSDUMP output.

Please let me know what other information you may need.

=========== script =================
<html>
<body>
<?
# The following line contains the SQL server hostname, the username, and
# the password for connecting to the database.

$db2 = mssql_connect("cfs_back","daf","987654321")
or die("Unable to connect to MS SQL server");


# The next line says which database to use.

mssql_select_db("dupcsm",$db2)
or die("Unable to select database");

$result = mssql_query("Update Customer set Address_Line3='jjjjjjj' where
Customer_Id='80110'",$db2);

?>
<p>test<p>
</html>
</body>
========== end script ===============
========== dump log =================
