Hi, I left my tmux sessions live while I was away for 2 weeks and saw that the tmux_fork_proved file was created.
Here are the info
pparissis at poseidonas in ~ *130
ls -ls /tmp/tmux_fork_proved
0 -rw-r--r-- 1 pparissis pparissis 0 Apr 15 05:37 /tmp/tmux_fork_proved
pparissis at poseidonas in ~
cat !$
cat /tmp/tmux_fork_proved
pparissis at poseidonas in ~
attached files
tmux.fd = lsof for tmux process
tmux.server.info = output of tmux info
I know that Nicholas has already reported that he fixed some leaks, but I
thought it could be useful for Kezes.
Cheers,
Pavlos
