Recurring exception in a Smack's thread

Hello everyone,

I've been using Smack to create a Facebook's chat at my website. The users can login in their account and connect with the Facebook's Chat inside our website. So, there are concurrently a lot of users using the chat.

It's been working ok until now. This night, at 04:00 am, the server stoped responding. When we saw the log, there were a lot of exceptions of the same type happening recurrently, like it was a loop. Since there's none of our classes in the stacktrace, I think it was happening in one of the Smack's threads.

This is the stacktrace:

java.io.EOFException: no more data available - expected end tag </stream:stream> to close start tag <stream:stream> from line 1, parser stopped on END_TAG seen ...</mechanisms></stream:features>... @1:349

Thanks in advance of the attention.
