That makes me think about something, specially since Carl mentioned that 
there are children involved.

Maybe we should also investigate if the SegFaults are simultaneous with 
anyone specific entering the room where the servers are.  Like someone 
bringing coffee or pizzas or so ? I swear that I have seen some 
long-running applications mysteriously fail as soon as some specific 
end-users approached a keyboard.  They did not have to even touch the 
keyboard for this to happen.
There are programmers like that too, for that matter.

Surprise visits by big bosses are also among well-known triggering 
factors, as are demos to new users.  But I think in this case we can 
eliminate the first one, since the problem happens several times per 
day.  After the first couple of visits, the surprise element would tend 
to disappear.
