[WARN]Failing because we have 4063 connections already. Please read doc/TUNING for guidance
Hi all,
since I upgraded the torland relay from 2.6.7 to 0.2.7.6 I get the following warnings:
09:20:30 [WARN] Failing because we have 4063 connections already. Please read doc/TUNING for guidance. [101144347 similar message(s) suppressed in last 21600 seconds]
Google only spits out https://trac.torproject.org/projects/tor/ticket/16929 which does not help me. I don't find the mentioned branch bug16929 in git.
Can someone please advise what has to be done to avoid the warning, or point me where I find can the file "doc/TUNING".
Thanks

Thanks Jonas for the link. file descriptors should be set to ulimit -n 65535 in the tor startup script. I thought that would work. But checking /proc/PID/limits I saw that file descriptors were actually limited to 4096.
I increased fds via sysctl. Now the warning is gone.
Hi,
I think it's a problem of amount of file descriptors : depending on the user, you have a limited amount of file descriptor that can be used (inside the tor's code, file descriptors are also used as handle/identifier for all network connections).
I think the max amount of it (for a given user) can be checked with the command "ulimit -n" as this user.
When I had 2 tor clients running (the second launched manually by a user named "tor2"), I modified the "limits.conf" file, adding those 2 lines at the end :
#* soft core 0 #root hard core 100000 #* hard rss 10000 #@student hard nproc 20 #@faculty soft nproc 20 #@faculty hard nproc 50 #ftp hard nproc 0 #ftp - chroot /ftp #@student - maxlogins 4 tor2 soft nofile 100000 tor2 hard nofile 100000
May be it needs a restart, or it doesn't apply to what have been started by "tor2" user before the modification When tor is launched by /etc/init.d/tor start may be this haven't to be done manually.
That's all I know about it, hope it will help you to find and correct the problem !
Best regards, Julien ROBIN

Thanks Julian for the hint. I adjusted limits.conf accordingly, so the users that run the tor processes get increased number of fds.

Are you using tor packages from https://deb.torproject.org/torproject.org/dists/ ?

I get packages via deb https://deb.torproject.org/torproject.org precise main
But I use a custom startup script from torservers, that is able to handle multiple instances. It should set ulimits -a 65535 but that seams not to work. After I increased it via sysctl, the warning is gone.
