Does Smack API have a throttle/input rate limit mechanism?

Hi all,

Does Smack API  have a throttle/input rate limit mechanism? I ask because if I get lots of messages in a short abount of time, it looks like Smack sends them back to the server with an XMPP error status.

Assuming there is a throttle mechanism, is there a way to control/deactivate it? If it is not possible to do so where is is located? I was not able to find it in the code.

Thanks,

Gabriel
