kernel CAN'T EMERGE -- "Too many open files" HELP!

patty.yivi · May 18, 2016

Please review and help if you can.

Below there is reports of failure for trying to emerge debian, vanilla and gentoo sources.

As you can see the core issue is caused by:

"Too many open files"

How to control allowed number of open files?

Q: Did you achieve first boot with the default debian-sources - or are you just trying to get to first (initial) boot?

Q2: Do you have hardware or a filesystem not supported by the stock debian-sources kernel?

patty.yivi · May 18, 2016

So far I've booted with the previous kernel, compiled yet within gentoo system, namely: gentoo-sources-4.4.0-r1

I've normal laptop, Lenovo Y550, with nvidia and intel cpu, and filesystems on my computer are: xfs (root '/'), reiserfs (portage, ccache), ext2 (tmp, /var/tmp), ntfs (miscellaneous data) and ntfs is mounted as ntfs-3g

Besides, also no other kernel brand wants to EMERGE (install), including gentoo-sources.

Gentoo kernel so far has worked, emerged and compiled well, but after switching to Funtoo can't emerge at all.

Also to mention /var/tmp free space is about 19GB, and maybe more when renewed attempt of installing (emerge -v debian-sources) pures what left from the previous one.

Oleg Vinichenko · May 20, 2016

i'm not entirely sure but maybe you hitting ulimit problems. Do you have ulimit specified anywhere? ulimit -n shows it.

But i guess dirty workaround could be:

rm -rf /var/tmp/portage

patty.yivi · May 21, 2016

ulimit -n

yields:

1024

How to handle ulimit at all and what to do next with this value, please?

Oleg Vinichenko · May 21, 2016

this value is much lower than default, which is 16000 for open files. Normally this defined in /etc/security/limits.conf. There're several ways to change the values but first of all try to find out why you got unusual value. Did you change that?

patty.yivi · May 21, 2016

As might already presume this is the first time I hear about it at all ;)

What's more there isn't anything like /etc/security folder at all on my system.

Wait, has it anything to do with pam? I entirely resigned of emerging pam and set use flags for it for ebuilds not to incorporate pam dependencies...

patty.yivi · May 21, 2016

After doing some research about ulimit and linux limits at all through Google etc. have tried set such two configuration files:

/etc/security/limits.conf

*              hard    nofile          1028096
*              soft    nofile          1024000

and

/etc/limits

* N1024000
sysadm  -
root -
portage -

however, after logging out in in it has taken exactly no effect:

# ulimit -n
1024

In order to make possible emerging debian-sources, have done simple thing: ulimit -n 1024000
and it works:

# ulimit -n
1024000

of course just within the login session, and then it flees.
It helped to emerge debian-sources, but the problem of setting the limits values which would survive system reboot is still intact.

patty.yivi · May 22, 2016

------ EDIT:

It turns out settings abovementioned work! :)

Those in: /etc/limits

while these in: /etc/security/limits.conf bring absolutely no effect!

However only after rebooting computer they've came into effect, not just after logging out and in as people write in tutorials...

And they hold just for graphical terminal, for ordinary user or when made su, for the text console when logging in as root it still says:

# ulimit -n

1024

[\code]

but ordinary user's console respects these settings.

Oleg Vinichenko · May 22, 2016

good. but what was the original problem? did you manually change the limits before? default values (not like yours) certainly enough for merging debian-sources. what i'm trying to figure whether it's manual change or not.

patty.yivi · May 22, 2016

As you probably read already about the original problem is covering from Gentoo.

As you can see step by step it succeeds iteratively solving such issues like the abovementioned. Previously as yet branded as Gentoo the system worked well without any limits settings. Conversion something introduced.

Funtoo's sys-libs/pam-1.1.8-r2.ebuild changes limits.conf:

# setting default number of open files to 16000, with the ability to
# push the limit up to 64000. This provides reasonable defaults for modern
# systems that need to handle things like slowloris in defaultconfigs.

echo "* soft nofile 16000" >> ${D}/etc/security/limits.conf || die "limits set fail"
echo "* hard nofile 64000" >> ${D}/etc/security/limits.conf || die "limits set fail"

Oleg Vinichenko · May 23, 2016

ok, so this is yet again using existing install. please. install Funtoo from fresh stage. Converting existing Gentoo installation into Funtoo is unsupported (though, theoretically possible). You are hitting various discrepancies due to that, and this is not really Funtoo bug.

patty.yivi · May 23, 2016

It looks like only this one is yet on the battlefield, actually, and the fresh install with compiling everything anew seems too cumbersome, not worth it.

patty.yivi · June 1, 2016

ulimit -n 1024 is set 1024 on Gentoo as default value, probably such a security measure.

However interesting why Gentoo can emerge kernel with this and Funtoo can not?
