Well, compile up tmux with "-g -ggdb" and see if it core dumps.
More thank likely though, I suspect what's happening is that tmux, over
time, is spawning many jobs through its status-{left,right} scripts --
presumably leading to some kind of potential fork-bomb, although your OS
might be clever enough to handle this by killing the parent process; in this
case tmux.
This isn't a new problem, if it turns out to be true. Byobu has this
problem, and one way of trying this out is to increase your status-interval
setting within tmux to something quite high -- the down side to this is that
your updating of information from within tmux will suffer, but that's a
small price to pay.
I do have some patches which I really do need to clean up and submit here,
to give each job its own interval-rate. This would solve such a problem.

See above. A stack trace from a corefile if you can get it would be
helpful. If not, enabling tmux with "-vvvv" and sending though the
tmux-server-*.log file is also helpful.
