I got "cannot connect" error when I did stress test for a project we did
recently. We used Apache Jmeter and there were 5 concurrent connections in a
second.
Initially, I thought it could be because of MySQL, becuase the first page of
the project runs a lot of queries.
Then I did the simple script below and start Jmeter once again.
<?
$conn = mysql_connect ( '10.0.1.4', 'root', '') or die("Could not connect: "
. mysql_error());
mysql_select_db('lub2', $conn);
$res = mysql_query("SELECT * FROM pages_lv0 WHERE id = 1", $conn) or
die("Invalid query: " . mysql_error());
mysql_close($conn);
?>
I got the same error again and checked MySQL server. I managed to connect to
the server and noticed that it is woriking fine, but I still was unable to
connect to the server via the script. I moved MySQL database to our Linux
server and repeated the test. The result was the same. Then I moved the PHP
script to the Linux server and run test once again. I did not get the error.
I moved database back to windows, left PHP on Linux and run the test. No
error. I compared settings in php.ini on both Linux and Windows and they
were the same. So I conclude this is PHP bug or feature under the Windows
platform.
Does anyone met the same problem before? I searched for the answers in the
newslist, but did not find anything related to the same type of problem. I
found one post in the bugs database (and I already submited this problem as
a bug), but support team said it is not a bug.
