Can any one know which made my hosting overload? by vB or high traffic or ddos attacks?

Thanks

How many plugins do you have installed? The more plugins you install, the more load is used by the forum.

Whether it's a DDoS attack or not is not something we can answer, you host should be able to see that.

Looks like an overactive plugin causing strain on hosting.

It depends on your hosting. Even sending out an email to a few hundred users can get you into trouble with some hosts.

Who is your host? Perhaps it is tome for an upgrade?

PS-If it was a ddos attack it would be easy enough to see in your connection logs and chances are your host would have pointed it out if it was the cause.
