Known problem. Fix is in 2.8pl0. Patch was issued to list; you will
find it in the archive. Attached. Buffer overrun in udp_tx(). Only
seen when number of players exceeds 14 or so.

You fail to understand the new solicitation code ... it does not matter
at all whether the metaserver is up, the solicitation packet is sent
anyway. There is only one packet sent, unlike a TCP connection which
requires three just to establish the connection.
