Is there a way to find out why tmux crashed

I am trying to shift from using VNC to tmux. My tmux keeps crashing at least once in a week and I am clueless why this happens. VNC rarely crashed and this weekly crash is a strong detrimental for me to completely switch.

Is there a way I can find out the reason tmux crashes ? My .tmux.conf is pretty simple

 #Don't show the green ribbon below

 set -g status off                                                                                                                                                                                           

 #Select panes by mouse click                                                                                                                                                                                

 set -g mouse-select-pane on                                                                                                                                                                                 

 #enable scrolling by mouse in tmux

 #enable resize of pane by mouse                                                                                                                                                                             

 set -g mouse-resize-pane on

I use iterm2 with terminal mode set to 256 color and heavily use vim plugins and colorschemes(Lid, nerdtree, tagbar, indentLine, molokai etc.,). To adjust terminal color I had following setting in my .vimrc but I am not sure if these are in any way related to tmux crash

set t_ut=

set t_Co=256

Also, I have enabled mouse in my vim set mouse=a

Is there a way to find why my tmux session is crashing ?

Can you start tmux using tmux -vvvv ? It will give you a logfile in the same directory called tmux-[...].log. Try to reproduce the crash and as soon as it crashes, post the last X lines of your error log here :)!

Can you start tmux using tmux -vvvv ? It will give you a logfile in the same directory called tmux-[...].log. Try to reproduce the crash and as soon as it crashes, post the last X lines of your error log here :)!

@polym I have attached the logs to the question after tmux has crashed

Can you start tmux using tmux -vvvv ? It will give you a logfile in the same directory called tmux-[...].log. Try to reproduce the crash and as soon as it crashes, post the last X lines of your error log here :)!

This may/will depend on the distro you're using, and whether or not debug/dev packages for tmux are installed, and whether or not it would dump core (if the OS settings permit it to). If it dumps core, and you have a debug version, you should be able to narrow the reason for the failure down quite nicely.

I found this in the readme on the tmux github page.

"For debugging, running tmux with -v or -vv will generate server and client log
files in the current directory."

In other words, unless you explicitly told it to log, it won't.
