Limited number of ports
Windows systems have about 4,000 ports available for client connections,
and after a connection on a port closes, it takes two to four minutes before
the port can be reused. In situations where clients connect to and disconnect
from the server at a high rate, it is possible for all available ports to be
used up before closed ports become available again. If this happens, the
MySQL server will appear to have become unresponsive even though it is
running. Note that ports may be used by other applications running on the
machine as well, in which case the number of ports available to MySQL is
lower.

[Ofcourse, MS KB has registry fixes for this ;) ]
