Author/maintainer of Byobu here... Tell me more about your "byobu crash". Can you point me to any bug reports in either bugs.launchpad.net/byobu or github.com/dustinkirkland/byobu ? Thanks! @DustinKirkland
If I have the time, though, I'll fire up byobu and see if I can make it happen again. I tend to leave sessions open for many months and it wasn't something which happened on a regular basis, and I never experienced it with bare tmux.
