We have now had 2 more failures of the tcp listener on 2 seperate 
servers in the last week, a simple reload of the software fixes this. 
the thing I have noticed when this occurs is that when telnetting to the 
port you can then type in anything and try and escape, etc but the 
connection never closes, whereas on a working server the session will 
close after a short while of typing and pressing Enter.

The logs do not show anything or give any pointers as to the cause...
