Hello Diana, thank you for your reply.
I have dowloaded compiled and tested the release 3 of Yate from SVN 
and yes the number of severe flood detected messages is now 
Another great improvement I found is to change the priority of thread 
YateSIPEndPoit to High.
With this change, the severe flood message disappear completly but I 
don't know the consequence of this change.
Can be this a problem?

Hello Lerto,

Some of those patches have been pushed lately into Yate 3 SVN. So 
upgrade may help.
