Git repo problem?

Hi,

Today I saw an wired error message when I tried to push:

t-ishii$ t-ishii$ socksify git push
X11 forwarding request failed on channel 0

   9d7c5baf..d1a2e366  V3_7_STABLE -> V3_7_STABLE

It seems the commit was pushed successfully
(https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commit;h=b9ee8417ea74798c108498849d453e693246c3a1)
but the commit mail did not delivered.

Is there anything I need to care?
