Xen Debian VPS Problem With nash-hotplug Using 100% CPU Resource
Recently I setup a Debian 4.0 VPS using xen image from jailtime.org, once the VM running I noticed that the load goes 1.0 all the time which make the VM very slow. From top command you’ll see the nash-hotplug process is the cause.
First you can kill it by execute the ‘kill -9 <process id>’ command (without the quotes), where <process id> is the process id of nash-hotplug. Then to automate killing the nash process every time you reboot the VPS run these commands:
PHP Unable to Connect to MS SQL Server Express Edition
I’ve been struggling for several hours to find out why PHP 5.2.5 didn’t want to connect to MS SQL Server 2005 Express Edition although extension=php_mssql.dll already enabled and phpinfo() is showing MS SQL already active.
I always got this error messages when trying to connect to MS SQL:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: (local)\SQLEXPRESS in path\mssql.php on line 5
After doing some searching, I got an answer that PHP 5 is using old ntwdblib.dll version. The one that comes with PHP 5.2.5 distribution is version 2000.2.8.0 which seems doesn’t compatible with the new MS SQL Server 2005 Express Edition. I downloaded new dll from http://webzila.com (use the search tool) which is version 2000.80.194.0 and replaced the one on PHP folder with this version.
I use this code to test the connection and its working:
echo("Testing MS SQL connection... "); if ($conn = mssql_connect('(local)\SQLEXPRESS', 'user', 'pass')) { echo("Connection succeed"); mssql_select_db('dbname', $conn); mssql_close($conn); } else { echo("Connection failed"); }

ok, do this at your own risk backup your mysql data first!

Xen VPS “4gb seg fix up” Problem
It's a known issues on Xen based Virtual Private Server (VPS) that often it shows "4gb seg fix up" error messages. After a few search I found this command to fix it.
Run the commands below on DomU
First try disabling tls by renaming it to tls.disabled:
mv /lib/tls /lib/tls.disabled
mv /usr/lib/tls /usr/lib/tls.disabledIf this doesn't work then try this command:
echo 'hwcap 0 nosegneg' > /etc/ld.so.conf.d/libc6-xen.conf && ldconfigafter that you'll need to restart the VPS
