I have noticed tmux locking up with my original tmux.conf when closing windows, likely because of renumber-windows on: set-option -g default-terminal "tmux-256color" set-option -g history-limit 3000 set-option -g renumber-windows on set-option -ag window-status-current-style bold set-option -ag window-status-current-style fg=black set-option -ag window-status-current-style bg=blue set-option -ag status-style bg=cyan set-option -g escape-time 50 I have since switched to a more simplistic config that hasn't run into the lock up, but I can still trigger it with movew -r as described above: set-option -g escape-time 50 set-option -g base-index 1 set-option -g pane-base-index 1 > > This started to occur in OpenBSD amd64 snapshots around July 13. > > I am running my OpenBSD amd64 with sysctl vm.malloc_conf=S > > ~/.tmux.conf > > set -g status-keys vi > set -g status-right "%F %R" > set -g status-style "bg=black,fg=white" > setw -g mode-keys vi > > Thanks. >
