Is there some throttling that doesn't work? I do not know how 'bad' the situation is now that we have the dirty page tracking stuff, still need to create a test environment. But the general idea is that its broken because the ACK from writeout can be delayed and the remaining free memory taken by other incomming network packets. Until I have a test setup and some reproducable deadlocks I cannot say more I'm afraid. Peter
