This is a bug in epoll on Linux, you have several choices: - Build tmux against libevent 2 and set EVENT_NOEPOLL=1 in the environment before starting it. (libevent 1.4 has a another bug which is worse, so only do this if you use libevent 2.)
- Avoid redirecting to /dev/null. IIRC you can workaround it with for example tmux info|cat >/dev/null. On Mon, Jun 27, 2011 at 07:00:30PM -0700, Jesse Molina wrote: > > Sorry.
