There is possibly a small timing hole.  Tim uses "ping" after any command
that might take a while to execute.  When the engine finishes, it then sends
a "pong".  As the thing first logs on, starting crafty can take a few seconds
while it sanity-checks the EGTB files.  If a match comes in before crafty says
"pong" then xboard rejects the match request immediately...

perhaps that is what you are seeing... another program is issuing a match very
quickly and xboard/engine are not quite ready.
