In my experience this has been due to destroying sockets before cancelling 
the call into some socket function. Most of mine are preceded by recvfrom 
failed: or select failed:. There is not much we can do about this, except 
change the way we kill the server. The randomness is directly connected 
to which threads get ran in which order, and how socket functions are 
handled. I generally have not thought much of it, since I did want it to 
stop!

Not sure what you are saying here. Define "wprks nicely".

Define this more I have no idea what you mean, "less stable in 
bandwidth"
