Attacked maybe? A few server errors (220 of them) for 4 hours, but everything AOK...
 

Subject basically says it all. For some reason for the first time ever I got about 220 error messages between two vbulletin communities I own, one that is brand new (and hardly any traffic) and another with 10K members. This was between about 2AM and 5:30AM our time but they went away and everything seems to be functioning 100% as if nothing happened. Here are the messages, let me know your thoughts!

No indication that this is related to an attack.

The first 2 errors should be solved if you repair tables, see below.

See the manual on hte 3rd error: Can't connect to local MySQL server through socket

Repairing tables:
To fix this run Repair/Optimize in the Admin CP. You may need to run it more than once to fix all errors:

Admin CP -> Maintenance -> Repair/Optimize Tables -> Check All -> Continue

If you can not access your AdminCP, then you can upload the tools.php file from the vbulletin .zip file do_not_upload/ folder into your forumdir/admincp/ directory and run it through the browser, there's a switch there to run optimize and repair. Run it a few times for best result.

If you cannot access either the Admin CP or tools.php you can also use a tool like phpMyAdmin to repair tables.

Awesome, thank you.. I am the admin so not a problem to get in there...

There is also one more error I keep getting which is related to 'max user connections' which I think is a hosting issue now that our forum is getting larger. I'll post that sometime as well. I have a feeling its just a server error...

The final error simply means the forum could not connect to mysql, most likely because it was not running.
