asterisk users - Mar 2005 - Got 200 OK on REGISTER that isn't a register

What does that mean? Where can I get more info about it?

It means Asterisk received a 200 OK response to a REGISTER request, but 
it no longer has any evidence that it sent out that REGISTER request.

This can happen if the 200 OK arrives very, very late, or if it's been 
corrupted, or if the registrar doesn't respond with the proper headers 
to be able to match to the original request.

What does this warning mean?
