Try specifying a small value such as 32 for the reserved-sockets
option:
options {
reserved-sockets 32;
...
};
But, even if this seemingly solves this error, I suspect the above
error indicates that your OS has a fundamental limitation on the
number of file descriptors and will soon trigger a different type of
trouble. If you've not done this yet, I'd suggest you check the OS
capability with the tool I posted a few days ago, which is available
at http://www.jinmei.org/selecttest.tgz
One more thing: as already pointed out, if you specify a specific port
using query-source:

you effectively disable any security feature of P1 or P2 or recent
beta versions. Using these versions with a specific port doesn't
provide anything new and is meaningless.
