<DIV><FONT face=Verdana color=#000080 size=2>why is is deemed long enough time.
Maybe it is too long or maybe too short. Bind recursor tells
clients that authority is server failure before waiting for 30s
without being responsed. So it is deduced that Bind think 120 is
too long. </FONT></DIV>

<DIV><FONT face=Verdana size=2>I think it's just a default value because it's
long enough time to determine a server has timed out.

<DIV>According to rfc2308, if a server
has not responded to an outstanding query within 120 seconds,
the server may be deemed to be dead or unreachable.</DIV>
