Unfortunately this can cause problems.  In my experience directing
tmux's STDERR do /dev/null causes that invocation to hang on Linux
apparently due to a bug in the epoll implementation.  This can be
worked around by setting EVENT_NOEPOLL environment variable to 1
before starting the server, but if tmux is using a version of libevent
before 2.0 (which is quite common) that will occasionally cause the
tmux server to die.

There's a thread about this on the tmux-users mailing list:
