hmm is this something happening regularly with different servers or you have one server here you are looking at? On Wed, Sep 21, 2011 at 01:11:46PM +0200, marcel partap wrote: > >This is weird > indeed ^^ > >Can you send "tmux info" output? > Yes we can C: > tmux 1.6, pid 8196, started Sat Sep

This is weird indeed ^^ Can you send "tmux info" output? Yes we can C: tmux 1.6, pid 8196, started Sat Sep 17 04:32:41 2011 socket path /tmp/tmux-0/default, debug level 0 system is Linux 3.1.0-rc4-00131-g9e79e3e #27 SMP PREEMPT Thu Sep 1 12:05:51 CEST 2011 x86_64 configuration file is /root/.t

This is weird, either epoll is returning EPOLLHUP but read() is returning EAGAIN not 0 or an error, or epoll is returning EPOLLIN and read() is always returning EAGAIN. Can you send "tmux info" output? On Tue, Sep 20, 2011 at 03:47:26PM +0200, marcel partap wrote: > On 20/09/11 14:40, Nicholas M

Hi there :) This is a strange thing, sometimes tmux totally pwns one CPU, just noticed it has been consuming bloody 30hours of precious 2.8GHz processor time that should have been going to BOINC *grrr* ^^ anyways, a crude statistical analysis after detaching all clients > sleep 10s && killall -v
