Interesting, is that whats causing the problem? I'm curious to hear an explanation. Thanks!

Re: Tmux starts slowing down badly after long periods of execution
this has been covered before, tmux runs status-left and -right through strftime(3) itself so you are asking it to run a new command like 'date +"Wed Mar 23 2011 17:01"' every minute. until very recently these commands were persistent so each minute it would allocate a new job entry and cause tmux to use a lot of memory On Wed, Mar 23, 2011 at 12:52:23PM -0400, Samer Atiani wrote: >Interesting, is that whats causing the problem? > >I'm curious to hear an explanation. > >Thanks! >Samer > >On Wed, Mar 23, 2011 at 11:46 AM, Nicholas Marriott ><[1]nicholas.marri...@gmail.com> wrote: > > Change this: > > set-option -g status-right '#[fg=black]#(date +"%a %b %d %Y %R")' > > To this: > > set-option -g status-right '#[fg=black]%a %b %d %Y %R' > > On Wed, Mar 23, 2011 at 11:20:31AM -0400, Samer Atiani wrote: > > � �I'm still getting this problem at least once a day and its > beginning to > > � �make tmux unusable for me.

Re: Tmux starts slowing down badly after long periods of execution
I'm still getting this problem at least once a day and its beginning to make tmux unusable for me. To summarize the problem again, tmux starts to freeze intermittently after periods of use ranging from 3-8 hours. During intermittent freezes, tmux doesn't act on keyboard events quickly, freezes for about 3-5 seconds then all pent up keyboard events would be acted upon (whether they are tmux commands or keyboard events to programs running in a tmux window). After every freeze, there is a period of 5-10 minutes where tmux behaves normally, and then I see the freeze again. The only solution to this problem is to close everything, including tmux, and restart everything. I installed Ubuntu 10.10 from scratch on two separate machines and installed tmux using apt-get. Even after I did that 'tmux -V' does not work, but I found out that the version is 1.3 by typing :info at tmux command mode. Here is how my usual tmux session looks like: 1- I run tmux in a custom compiled urxvt terminal, but I've also seen the problem happen in stock gnome-terminal that comes with Ubuntu 10.10. 2- I aliased tmux to tmux -2 to force 256 colors. 3- My usual tmux session looks like this: * 1 window for finch (a command line IM client) with activity monitoring turned on. * 2-3 windows with vim open in them editing files. * 2-3 windows with ssh sessions open in them. If you need my .tmux.conf file you can see it here: https://github.com/satiani/init/blob/master/.tmux.conf I'm willing to collect any more information you want me to, I love tmux and would be distressed if I had to drop it and go back to screen because of the frequent freezes.

Re: Tmux starts slowing down badly after long periods of execution
Hi, I package tmux for Debian which gets from time to time synced from Ubuntu. But as far as I know there is no version of tmux-1.4 in Ubuntu 10.04 (which has 1.1-1) and 9.04 (which has 0.8-5). So I assume you have received tmux from another source probably from Debian's experimental repository which has a fix for the EPOLL bug on Linux.

This has worked in every (packaged) version of tmux. There must be something wrong with your installation. Nevertheless I am interested if this bug is reproducible.

Re: Tmux starts slowing down badly after long periods of execution
tmux -V does not work indeed. But from inside tmux, I typed :info in the tmux command mode, and it showed tmux 1.4. Usually what I do is terminate tmux normally; I wait for it to unfreeze (usually takes about 5-10 seconds), then close all windows, and then start tmux again normally without any special settings. I'll try EVENT_NOEPOLL=1 tmux and let you know how that goes, I will need to leave the computer on overnight to reproduce this.

Re: Tmux starts slowing down badly after long periods of execution
How do you get the version? I tried tmux -v and tmux --version, none of these worked. Anyway, I did the following: /home/satiani$ strings `which tmux` | grep tmux tmux 1.4, pid %ld, started %s looks like its version 1.4?

Re: Tmux starts slowing down badly after long periods of execution
If tmux -V doesn't work it isn't the released version of 1.4. Does killing tmux entirely then starting with "EVENT_NOEPOLL=1 tmux" fix it?
