Server procesing more virtual hosts:
grep -c VirtualHost httpd.conf  --> 3290

/etc/freetds.conf

[TEST1]
  host = 192.168.111.209
  port = 5000
  tds version = 4.2


the PHP script produce segmentation fault:

<?
$DB_SERVER = "TEST1";
$DB_LOGIN = "tes3000S";
$DB_PASSWORD = "test3000s";

$conn = sybase_connect($DB_SERVER, $DB_LOGIN, $DB_PASSWORD) or
die ("cannot connect"); echo "Success6";

exit;
?>

backtrace core: ( cut loading libs and symbol), the bt command
show only:

#0  0x004e39cf in tds_put_buf (tds=Cannot access memory at
address 0x9 ) at write.c:201
201             return tds_put_byte(tds, cpsize);


where is problem ?
thanx
