PADD 3.8 crashing pi-hole #252

Gothico74 · 2022-07-27T04:59:06Z

After upgrading from 3.7.1 my pi-hole (raspbian) to 3.8 i get an error: pi hole Disk shortage (/var/log/pihole/FTL.log)
after digging around i was able to find out that the ftl.log was 15Gb big and growing.
raspbian was running out of space and my Raspberry was crashing after two hours.
i deleted the file and it got another two hours.
after reverting padd back to 3.7.1 my system runs now 10hours and still up.

also screen (design) issues

long url's splitt in two lines, breaking the design
after the ipv6 adress is an empty line.
so i am missing two lines in my display

Gothico74 · 2022-07-27T05:00:36Z

forgot. pi-hole is updated to latest version also raspbian (buster)

yubiuser · 2022-07-27T06:45:49Z

What errors or lines fill the ftl.log?

Gothico74 · 2022-07-27T10:57:22Z

i wasn't looking into it. raspbian was very unstable and could freeze any moment, so i deleted it as fast as i could.

I am having the same issue FTL.log grows many many GB in several hours. PADD v3.8, latest Pi-hole.

In FTL.log the following line appears approximately 15 times every 0.001 seconds!

An info message about Telnet
WARN: Could not accept() in listener() (/_w/FTL/FTL/src/api/socket.c:267): Socket operation on non-socket

Looks like a communication error between PADD and Pi-hole and Pi-hole is logging the failures.

Perhaps to do with the new API endpoint for the gateway? That uses telnet, right?

Same issue with my install on RPi Zero W2.

cmdshft · 2022-07-28T04:53:37Z

Interesting that I have this issue on one Pihole but not the other, both were on latest versions of everything at the time of this comment. My Pi3b+ pihole had ftl.log at 20GB, but my Pi4 only about 8Kb. Not sure why there was a difference. However, the pi4 pihole crashed early this morning without my knowledge around 3am according to the 24hr log and my Pi3 pihole crashed 3 hours after that. I am currently downloading the 20GB FTL.log file to see what I can find. I am thankful I have 32GB of RAM now haha

Could you please try to manually edit the following line

PADD/padd.sh

Line 113 in 380636a

echo ">$1 >quit" | nc 127.0.0.1 "${ftl_port}"

To

data="$(echo ">$1 >quit" | nc 127.0.0.1 "${ftl_port}")"
echo "${data}“

jbutters110 · 2022-07-28T11:13:34Z

The issue only begins for me after a few hours of running Pi-hole & PADD.. i.e. for an hour or so everything will work fine, but then after an amount of time FTL.log will begin to grow with the message:

WARN: Could not accept() in listener() (/_w/FTL/FTL/src/api/socket.c:267): Socket operation on non-socket

Gothico74 · 2022-07-28T14:59:25Z

Well back from work i changed the line.
Waiting, for now the logfile is a few kb small.

mejndp · 2022-07-28T15:06:23Z

Same issue as above. Clean install of raspbian (console only). Couple of hours of removing the FTL.log file and rebooted, Below is what the log is showing before telnet went haywired.

FYI - I made the changes to line 113 above AFTER and will report back if the issue is still ongoing.

polyclementc · 2022-07-28T20:44:38Z

Hello, got the same issue as you. May I ask you what command to use to come back to PADD version 3.7.1 please?
Thank you

twerthi · 2022-07-29T00:55:38Z

Same issue here. pihole-FTL Log file grows astronomically quick, turning off PADD seems to resolve this.

mejndp · 2022-07-29T01:31:53Z

turning off PADD seems to resolve this

Hmm... interesting. I went ahead and disabled PADD (by deleting the launch script from .bashrc) then rebooted. We'll see if that is the suspect on my end.

Confirm. Disabling PADD did the trick. No more non-socket error messages.

yubiuser · 2022-07-29T07:10:31Z

We are still investigating. Cleary, there is an issue here, but we are not sure yet if the problem is within PADD, FTL or both. It's hard too reproduce because it does not affect all installations and usually does occur only after PADD has been running for a longer period of time.
To mitigate, you can run PADD v3.7.1

mejndp · 2022-07-29T07:19:30Z

To mitigate, you can run PADD v3.7.1

What's the proper commands / methods to downgrade and what's the URL? Many of the google search are pointing to a much older version - v3.2.1

yubiuser · 2022-07-29T07:27:22Z

This is the raw file
https://raw.githubusercontent.com/pi-hole/PADD/v3.7.1/padd.sh

Download and replace your PADD.sh

yubiuser · 2022-07-29T16:05:06Z

The only two changes we made regarding the FTL telnet connections are the two new GetFTLData calls

DHCP_ROUTER=$(GetFTLData "gateway" | awk '{ printf $1 }')

def_iface_data=$(GetFTLData "interfaces" | head -n1)

DL6ER · 2022-07-29T18:01:04Z

If you want, you could check my idea to remedy this (especially the "astronomically quick" FTL.log growth) by running

pihole checkout ftl fix/socket_simplification

You can always go back to the previous state by running

pihole checkout ftl master

yubiuser · 2022-07-30T13:44:30Z

pihole checkout ftl fix/socket_simplification

There was an update to that branch, if you are using it, please run pihole -up

howardsun-dev · 2022-08-01T15:46:10Z

Thanks, I am also having this problem and one of the side effect of it is it generated a 27GB FTL.log and forcing my pihole to stop running.

baz069 · 2022-08-01T16:33:14Z

Thanks, I am also having this problem and one of the side effect of it is it generated a 27GB FTL.log and forcing my pihole to stop running.

Exactly the same here, once the disk is full with the massive FTL.log the pi crashes. Rolled back to PADD v3.7.1 as suggested above and the log only reaches a matter of kilobytes.

It would appear that the issue is being worked on, but is currently on hold pending an 'unresolved conversation' (not sure what that means) - pi-hole/FTL#1396

yubiuser · 2022-08-01T17:46:24Z

pi-hole/FTL#1396 together with #254 should prevent crashing of FTL when using PADD 3.8.0.

Once the FTL PR has been merged, it's part of the development branch which will lead to the next released FTL version. We target an release in the not so distant future.

It's probably because the FTL log is so bit b/c of this bug. Just copy cp /dev/null /var/log/FTL.log to zero it out.

Hi, I am having the same issue of no space left on device, but running the cp /dev/null command above does not seem to allow it to download. Any ideas?

ChappyEight · 2022-08-04T15:40:16Z

This worked for me; (Removes packages and dependencies that are no longer required and deletes query log history)

sudo apt-get clean

sudo apt-get autoremove

sudo service pihole-FTL stop

sudo rm /etc/pihole/pihole-FTL.db

sudo service pihole-FTL start

But, I'm a novice so that may not be advised. Someone else should chime in.

Hi, I am having the same issue of no space left on device, but running the cp /dev/null command above does not seem to allow it to download. Any ideas?

delete the log file completely, it will be recreated automatically.
sudo rm /var/log/pihole/FTL.log

Thanks, that worked. I was able to download the file, but now what do I do with it? Sorry, new to linux.

cd ~ wget -N https://raw.githubusercontent.com/pi-hole/PADD/v3.7.1/padd.sh sudo chmod +x padd.sh

reboot and you should be good to go

You're a goddamn genius. Thank you so much!

Where is padd.sh located in the docker image? I took a look at the dockerfile and have looked in the usual places within the image itself and haven't been able to find it. I'm running into similar freezing issues, my current FTL log isn't too large, but I'd like to verify the padd version and see if downgrading resolves my freezing issues.

It's not part of the docker image (yet: pi-hole/docker-pi-hole#1105)

Pi-hole v5.11.4 FTL v5.16.1 Web Interface v5.13
PADD 3.80

cmdshft · 2022-08-16T06:22:38Z

21 days... Any progress on this?

yubiuser · 2022-08-16T06:38:21Z

It's fixed already. The next Pi-hole version will include the fix.

turbodlr · 2022-08-17T17:43:39Z

So if I do pihole -up and it updates pihole I can go ahead and update PADD to latest version?

yubiuser · 2022-08-17T17:48:33Z

If your're still on v3.71 you should not upgrade PADD now. Once there is a new version of Pihole via pihole -up, it's safe to upgrade PADD as well. I have a number of PRs for PADD as well, so expect a v3.8.1 soon after the next Pi-hole update.

yubiuser · 2022-08-18T11:08:28Z

A FTL hotfix (v5.16.2) has been released just now. This specifically addressed the PADD v3.8.0 crashes. You can now upgrade your Pi-hole version and should be able to run latest PADD withouth crashes. The log spam should also be reduced, the remaining warnings like

will be addressed with the upcoming PADD v3.8.1
