I faced the sleep query issue sometimes. Many times that kills the server. When ever you are using dedicated virtual hosting server that time you need to me very careful how you are setting up the apache and mysql. we solved mysql sleep processes issue
mysql sleep processes issue solved
mysql sleep processes issue solved
I found some major reasons for mysql sleep processes. Here I am giving some reasons:
[viral-lock message=”Reasons and Solution is Hidden! It’s Visible for Users who Liked/Shared This article on Facebook or Twitter or Google+. Like or Tweet this article to reveal the content.”]
1. apache requests increase
2. mysql queries increase
3. mysql slow queries increase
4. apache connections start to wait on slow mysql queries
5. apache connections take longer to close
6. more apache connections are opened
7. with each apache request a new sleeping mysql connection is made
8. mysql & apache reach max_connections
9. server slows to a crawl
[/viral-lock]
Using linux top command you can check the load average and which process is taking so much memory of your server. If you saw mysqld is taking much memory of server then you should check using following mysql commands:
> show full processlist;
using this command you can check the mysql processes. Which sql queries being fired on mysql server. If you found so much sleep processes then you should check your mysql variables and settings. If so much mysql queries being fired on specific table then you should change the table storage engine type.
Using following command you can change the storage engine type.
> ALTER TABLE tablename ENGINE = MYISAM;
MYISAM storage engine type is faster then inodb. you can create the mediator tables also for big size table to handing a load of table.
Then major change for solving the issue of sleep processes is, you should change the wait_timeout variable. Default value is 2800 seconds.
mysql> show variables;
you can change the setting using following mysql command. Best value is 60 second need to be set for wait timeout.
mysql> show variables like ‘wait_timeout’;
mysql> set global wait_timeout=60;
mysql>show variables like ‘wait_timeout’;
After doing above changes you can check the mysql processlist. If you are still facing issues with mysql then please write to me.

Today when I logged to my wordpress blog account and looked at dashboard, I saw the new changed statistic graph.
The new statistic graph is looking really very cool. New graph version is better for those who are visually improved so nicely.
WordPress changed the statistic graph
For wordpress blogger and website users this news is really great.
Seeing this graph I must say you will miss having the grand total of both syndicated and on-site views for an entry.
As we know we need to updgrade the “WordPress.com Stats” wordpress plugin to see the updated stats in your hosted wordpress blogs.
You can download or update the wordpress stat plugin using following URL
http://wordpress.org/extend/plugins/stats/
WordPress changed the statistic graph
What wordpress is saying about changed Stat in Twitter.
Sexy Stats: http://wp.me/pf2B5-1n9
As per wordpress:
Each module can be opened and closed, moved, or hidden completely. If you don’t want to see a module, minimize it with one click or use the Screen Options to keep it out of sight. Customize everything and view stats the way you want to.
As you hover over each bar in the chart it changes color and displays a tooltip, giving you more information about the data. If the chart is showing data by day, Saturdays and Sundays have a light gray background to make it easier to see weekly patterns. Under the chart you’ll notice a new area, called “fortune cookies,” where we’ll highlight key stats.
During the redesign we went with bar charts because the end of one day and the beginning of another shouldn’t be connected. Each day starts at zero and we think bar charts work much better for this type of data. We hope you’ll agree once you get used to the change.
In this first phase of the stats redesign we’ve focused on the main page. This will allow us to collect feedback from you so we can tweak everything as we go. We’ve only mentioned a few of the highlights here, so take your stats for a drive around town to get used to the feel. Let us know what you like and what you might change. As we gather feedback we’ll apply a bit of sexy to the other stat pages.
