Getting a status message is the software letting you know that either you double-posted or tried to search too quickly. Every action on the forum takes a CPU cycle on the server, and so there are limits in place to stop automated indexing software (used by Google and the like) to overload our servers. If you act in a manner that appears to our software that you're not a human (e.g., trying to conduct a bunch of searches very quickly), then you get slowed down a bit... by things like this status message and the counters built in to the software.

It's nothing to be concerned about, worried, or what-not. It's just letting you know that you've hit a setting limit we've set and you need to follow whatever it's telling you in order to not hit that limit in the future.
