To give some context WHM says load on this account (for MySQL) is currently 39.4. I've no idea what that means but it's way way higher than any other account.

How can you tell if its yahoo slurp? I expected it could be cuil but have searched for cool's IPs in todays raw access logs and they aren't present.

I only use google analytics for stats, does that contain a robots section, I couldn't find one.

That would be a 'too many connections' error.

You'll need to ask your host/server admin to increase this value.

As it's a dedicated server I am the server admin.

How do I do this. It's a WHM/Apache server.

For anyone else reading: The way I did this was by SSH (search for Putty.exe and download). Then CD ../etc. Then pico my.cnf. Then change from 500 to 1500. Then CTRL+X then Y and Return. Close putty.exe

This may have found (I'm not sure yet) a fix to the problem, but it isn't in itself a solution as it hasn't dealt with what caused the large bursts of MySQL connections which I think were robots.

How can I find out if my site is coming under a lot of robot activity?

install a robots mod with the updated spiders list.

Spiders on ForumHome - vBulletin.org Forum

spiders_vbulletin.xml system 1.2



1500 may be too high for your box. keep that in mind. it depends on ram more than anything.

http://dev.mysql.com/doc/refman/5.0/...nnections.html

mysql ships default with 100.
most people don't go above 500.


I just glanced at your site, and you aren't 'THAT' active. Something is running/looping on your server, or your getting ddos'ed or something.

check your apache error and access logs to see if there's anything weird going on.


you may have another issue with threads (not vb threads, but sql threads) failing to close properly.

besides stock vb and vbseo, what else does your server run? (other sites, vb addons, etc). It could be a poorly written script on a another site causing issues.

My server runs literally hundreds of sites.

The main traffic one being an online games one but that only uses MySQL once per day to make the static pages of the site.

The next biggest load on MySQL comes from a lyrics site with no traffic I run. I thought this might be a robots issue too.

I am encountering similar problem I am guessing...

Looking at the following code:

Quote:
Database error in vBulletin :
mysql_connect() [&lt;a href='function.mysql-connect'&gt;function.mysql-connect&lt;/a&gt;]: Access denied for user 'root'@'localhost' (using password: NO)
/home/gblcg.com/public_html/knowledge_share/upload/includes/class_core.php on line 311
Can anyone help pls?

Thanks.
