I think I've got something different. There's no evidence of a succeeded accept followed by a failed fork (which as I understand it is the essence of what was being described). I just watched an 'incident' just now, and for every succeeded accept, there was a successful fork. My hangup monitor showed an earlier hangup like this:

this shows the output of a call to netstat showing that a connection from a particular node was attached to the 'main' listener process (not a forked 'servicer'). The situation is rather confused by the fact that there is a permanently forked-off 'monitor' process (2029) that (I hope) isn't involved in any way in this problem. When this happens, the 'stuck' node is visibly 'stuck' to the listener indefinitely
