What does "HTTP was over run" mean that shut us down?

[David Copeland]

I got a response from our support that says:

"Looks like HTTP was over run. The server is rebooting
right now and should be back online in the next 10-20
minutes."

Questions

1) What causes this? (I'm a novice)

2) Our forum is shared with others. Our forum is
light with traffic. Is this the fault of another client?

3) When this happens, does the server just stall
and wait until someone notices? Or does it reboot
itself automatically?

4) Has anyone heard of netwhistle.com ? They offer
a free service to monitor and notify. Good? Bad?

Thanks,

David
