I'm kind of curious how cabling issues like the above happen and if there 
is something, either procedural or technical, that can be done to improve 
reliability of cabling.  Given the number of connectorized cablings that 
the (E)VLA has (10^4 to 10^5 or so, perhaps), if every cable has on 
average one failure in its lifetime of say 30 years, that would be 1 to 10 
cable problems every day!
