Ok quick follow-up. I just figured out the problem based on info from the message board software user's group. In the past these errors have occurred with ddos attacks. I think what's going on now is all the bot activity (probably AI bots) that goes on today... it's overwhelming the Who's Online table in the database.

There are two ways to mitigate this error, convert the table entry from memory to disk, or reduce the time period to capture who's online. I had that set to 10 minutes. So you'd see everyone online in the past 10 minutes.

For now I've reduced the time to capture who's online from 10 minutes down to 1 minute. That should alleviate the problem. If not, I'll convert the database entry for who's online from memory to disk.
