Linuxgsm: Updated LGSM. Now seeing "numfmt: invalid number: 'K'".

Created on 9 Sep 2018 · 38Comments · Source: GameServerManagers/LinuxGSM

Describe the bug
Since updating LGSM on September 8 (using update-lgsm), some LGSM commands are showing numfmt: invalid number: 'K'. Servers seem to be running fine otherwise. LGSM version shows as 170305. Tried installing UT99server from scratch and that's also showing the same error. Updated my other server (UT2K4) using update-lgsm and it's showing the same error.

To Reproduce
Steps to reproduce the behaviour:

Update LGSM with update-lgsm.
Issue an LGSM command, such as DETAILS.
Examine the results.
See error: "numfmt: invalid number: 'K'" in the results.

Expected behaviour
No error messages.

* Minimum Information *
The game server I am running: UT99 (also UT2K4, also affected).
The link from ./gameserver postdetails command: postdetails did not work. Manual attempt to use hastebin also failed. Server details pasted below (first is before LGSM updates, second is after clean re-install of LGSM and UT99 server).

Additional context
Excerpt of command output showing error in context:

It's kind of a long shot, but I think the problem may be related to the new 'ansi' option. I've disabled ansi in my ut99 server config, and it had no effect: ANSI colours are still appearing everywhere. And some of the ANSI codes include 'K'.

jrmain on 9 Sep 2018

I think I know where the issue is but I'm on my phone so can't bring it up currently

dgibbs64 on 9 Sep 2018

I just reinstalled my UT2004 server from scratch and it's doing the same thing.

jrmain on 9 Sep 2018

I think its related to this https://github.com/GameServerManagers/LinuxGSM/pull/1971

dgibbs64 on 10 Sep 2018

Same for CS:GO server.

xxngle on 19 Sep 2018

Hi,
Having same issue since update LGSM for Project Zomboid Server to last version (180908).

Venopsis on 30 Sep 2018

I have same issue at insurgency and KF2 server

Troopie on 30 Sep 2018

I am aware of this issue. Should be fixed in next release. It doesnt break anything important :)

dgibbs64 on 30 Sep 2018

connects to #1971

dgibbs64 on 4 Oct 2018

I am not getting this issue. I think its related older distros like Ubuntu 14.04

Hello Daniel,

Here is the details of my server:

Distro:   CentOS Linux release 7.5.1804 (Core)
Arch:   x86_64
Kernel:   2.6.32-042stab120.18 (production) and 3.10.0-862.14.4.el7.x86_64 (testing server)

Let me know if you need more details to troubleshoot.

Venopsis on 15 Oct 2018

Odd I just tested the issue on CentOS 7 and the issue didn't occur

[root@li655-230 ~]# numfmt --to=iec --from=iec --suffix=B "$(grep ^MemTotal /proc/meminfo | awk '{print $2}')K"
3.8GB

dgibbs64 on 15 Oct 2018

Here are my details

Distro:    CentOS Linux 7 (Core)
Arch:      x86_64
Kernel:    3.10.0-862.11.6.el7.x86_64
Hostname:  li655-230.members.linode.com
tmux:      tmux 1.8
GLIBC:     2.17

Looks like you are only running kernel 2.6 which is really old

dgibbs64 on 15 Oct 2018

If I try the same command than your previous message, I don't have error:

But when using start command, I got error:

Suppose not related but no more able to run my server on CentOS since last update as Glibcxx 3.4.21 not found. Post open on Official game forum to check as nothing fix this.

I have two servers as mentioned (prod and testing). The testing one use recent Kernel (more recent than yours).

Prod is openVZ server based.

Just tried on testing and not having the issue at all.

Could be Kernel related? Not an expert.

Venopsis on 15 Oct 2018

Whats the kernel version of your testing server?

dgibbs64 on 15 Oct 2018

It is my guess that kernel 2.6 does not have numfmt or a very old version of it

dgibbs64 on 15 Oct 2018

what is the output of numfmt --version of the server that has the issue?

the oldest version I have available is

numfmt (GNU coreutils) 8.21

dgibbs64 on 15 Oct 2018

Not sure if you were asking me, but anyway: numfmt (GNU coreutils) 8.21.

jrmain on 15 Oct 2018

@jrmain odd I can't replicate the issue myself. I am unsure of what is causing the issue but it seems limited to old distros

dgibbs64 on 15 Oct 2018

Whats the kernel version of your testing server?

Hi!

Kernel:

Production (having issue) : 2.6.32-042stab120.18
Testing (not having issue) : 3.10.0-862.14.4.el7.x86_64

The production server is OpenVZ "VM" while testing is hosted on VMware Workstation pro.

numfmt (GNU coreutils)

Production : 8.22
Testing : 8.22

Venopsis on 15 Oct 2018

@jrmain odd I can't replicate the issue myself. I am unsure of what is causing the issue but it seems limited to old distros

I can look at the code. Can you provide any hints as to what I'm looking for?

jrmain on 16 Oct 2018

info_distro.sh

https://github.com/GameServerManagers/LinuxGSM/blob/master/lgsm/functions/info_distro.sh#L96

dgibbs64 on 16 Oct 2018

There's no MemAvailable in /proc/meminfo. If I change 'MemAvailable' in that command (run from the CLI) to 'nonsense' the same thing happens.

jrmain on 16 Oct 2018

Looks like MemAvailable was added to the Linux kernel relatively recently, in 3.14. I'm running 3.13.

Same here.

My distro:

Distro:    Ubuntu 16.04.5 LTS
Arch:      x86_64
Kernel:    4.4.0-042stab133.2
tmux:      tmux 2.1
GLIBC:     2.23

If additional information is needed, let me know.

Same with Debian 9.5 on Windows (WSL):

Kernel: 4.4.0-17134-Microsoft

I can't see a pattern to this issue currently

dgibbs64 on 24 Oct 2018

Maybe just stop using MemAvailable?

jrmain on 24 Oct 2018

Yes that may be the only choice

dgibbs64 on 24 Oct 2018

Replace with output from vmstat -s command?

Venopsis on 24 Oct 2018

Could always do a check - if it exists then use it, otherwise we can estimate it. The full calculation is documented here but do we need to be exact, or can we say 'if the linux kernel doesn't include MemoryAvailable then we estimate with the next best thing on the list?'
