Ok. I believe that I have resolved the issues that have been plaguing us since last Friday's upgrade to vBulletin 4.10 PL 2.
In attempting to address the symptoms, I made a number of changes to the forum, some of which I plan to keep and some of which I will roll back (and some I didn't realize until members reported it).
So ... if you are experiencing anything that you think I need to change, please let me know. And thanks for being patient as I worked through the issue.
For those who are curious and technically minded, the issue was a combination of a brute force attack by parties unknown using the search features of the forum combined with the back-end database using table level locking which allowed one attack query to take down the entire database as subsequent queries backed up and quickly consumed all available system resources waiting for a table lock release that never came.
I hope that with the latest changes we have seen the end of the issues. But please report any problems if you encounter them.
Thanks again!
John
