  We study the effect of a non-zero strange quark mass on the
color-flavor-locked (CFL) phase of high density quark matter. We have
previously shown that for a strange quark mass $m_s\sim m_u^{1/3}\Delta^{2/3}$
the CFL state becomes unstable toward the formation of a neutral kaon
condensate. Recently, several authors discovered that for $m_s\sim (2\Delta
p_F)^{1/2}$ the CFL state contains gapless fermions, and that the gapless modes
lead to an instability in current-current correlation functions. Using an
effective theory of the CFL state we demonstrate that this instability is
resolved by the formation of an inhomogeneous meson condensate, analogous to
Migdal's p-wave pion condensate. This state has a non-zero meson current which
is canceled by a backflow of gapless fermions.
