Is this a highjack attempt?

[Nintendo-Daily]

I received a database error email a little bit ago. Would someone mind enlightening me as to what this means. Is this malicious and would someone be able to add themselves without registering some how?

This is a server issue.
See this: http://www.vbulletin.com/docs/html/t...mysql_goneaway (http://www.vbulletin.com/docs/html/troubleshoot_mysql_goneaway) and this: http://www.vbulletin.com/forum/showt...265#post310265 (http://www.vbulletin.com/forum/showthread.php?s=&postid=310265#post310265)

Hmm...I'll get with my host I suppose. Thanks for being so prompt.

Would you mind doing me a huge favor?

Would you mind trying to register to see if it works? I haven't received any new members in quite some time.

Something is just strange about this to me.

Thanks for your promptness, vB Style.

I registered fine.

Interesting...thanks vB Style.

What do you think caused the error above?

Interesting...thanks vB Style.

What do you think caused the error above?

Could be a number of things.. have them check the settings in php.ini for max users and there's more, if they are a half-arsed decent host they will know what to look for otherwise there is recommended server settings at vb.com.

Hey guys, its me again.

This seems to be happening more and more often as of late and its becoming quite frustrating. Last week I received a ton of database error emails and got with my host about it. They said everything looked fine on their end. A day or two after submitting my trouble ticket to the host, the problem went away and everything returned to normal. I don't believe the host did anything to fix the issue because I received an email from one of the database admins where he asked me a few questions. I didn't respond to the email because I wanted to see if the problem fixed itself, and it seems to have done just that. I really don't think the host has anything to do with the issue. Here's why...

The location of my website is:

My forums and website use two completely different databases. I can navigate anywhere within my website without going to /forums and everything works perfect.

Whenever I start to receive all the database error emails, I get strange things like this:

Invalid SQL:

user.username, (user.options & 512) AS invisible, user.usergroupid,

FROM session AS session
LEFT JOIN user AS user ON(user.userid = session.userid)

WHERE session.lastactivity > 1279296520

ORDER BY username ASC;

I'm at the point now where I need some better direction because I really don't believe its a hosting issue. If anyone wants to help out with this I would really appreciate it.
