WAN periodically Rebooting

diyhouse

@Gertjan Yes many tx,.. I wondered if there was a parameter to limit log file size.
Although I had created at listing limit of 100000lines... it didn't seem that big.
One thing I might add the the wonderful pfsense dev. boys/girls,... is it would be nice to set the size limit in some more appro. units,.. eg meg bytes, or gig bytes,... pls
thankyou
BTW gone as big as system lets me,.. 2000000000bytes,.. or 2gigs as I recokon.. I have 99G free,.. but guess system is considering all log files,..

That a GUI setting.
100000 lines in a GUI is ... 'bad' as PHP is very low with 'thoudands' and things go downhill after hundreds of thousands. Until PHP breaks trying to show it.
Big log files are meant to be show 'on the command line'. Or use SSH+FTP = SFTP, which supports stuf like this in the blink of an eye.

Would be nice for the ones who are asking ... but never looked / found the log files.
The ones who 'know', don't bother, they go straight to the source, as things down there are the same dor the last several decades already ^^

Btw : huge log files are 'nice', because it gives you a big overview of what heppens.
But then pfSense has to rotate them, and that takes a lot of resource (CPU power etc) and not every pfSense has big drives, and endless write cycles, etc.
Running out of disk space is a known issue also.

@Gertjan Tx for the comments,..
I will drop the GUI max lines down though,...
BTW,.. Log files,.. where are they stored in the file structure?
this is my current file system

They are in /var/log. For the purposes of testing here I wouldn't worry about having larger log files but I would probably set them back when you're done.

@stephenw10
Just a quick up date,.. still waiting for a failure event,.. had been running for 15hrs+ then hit midnight Sunday forced WAN reset,.. 7.5hrs on the clock and counting,..
disk space still good,.. although I have used / lost 1gig of available storage..
But looking in /var/log I have this now as the big hitters on files,
I guess as folks have commented,. we'll see how much horsepower my cpu has to cope with the compression etc,.. when the file get rotated..

WAN has just fallen over @14:10
My the 'force' be with you,... ( hope this is the bits you need )
EDIT: replace txt file with compressed zip file

@diyhouse
Had to save file as attachment,.. as broke the 32K char. submission limit
Thanks...

@diyhouse
Just realised these statements entries are the indicators that things have failed, I think... IMHO,..

Aug 18 14:32:14	ppp	67004	[wan] OUT util: total 81% 10% 67% 109% 4% 39% 255%
Aug 18 14:32:14	ppp	67004	[wan] IN util: total 5511% 8% 8374% 0% 5% 7560% 17117%

So have gone back trough the logs pre 14:10...
PPP_PreFailog.zip
compressed Log file attached
As background,.. Netflix was in full HD stream,.. as well as streaming some YouTube,.. and there was an Alexa sound streaming going on as well...
And its just died again...
EDIT: changed file to compressed version

PPP_FullFAILlog.zip

Hope this helps some more,.. 2nd event will full events before and after

stephenw10

Hmm, that first disconnect looks different. It logged an LCP timeout which is more like what I expect:

[wan_link0] LCP: no reply to 5 echo request(s)
Aug 18 14:10:15
ppp
67004
EVENT: Processing timer "FsmKeepAlive" FsmEchoTimeout()
Aug 18 14:10:15
ppp
67004

It then reconnects 9s later.

[wan_link0] PPPoE: connection successful
Aug 18 14:10:24

Same thing happened on that last disconnect:

Aug 18 15:02:13	ppp	67004	[wan_link0] LCP: no reply to 5 echo request(s)

So both those are a reaction to the upstream server failing to respond to the LCP echos.
However I would expect to see those logged with the default logging settings and we did not see that previously.

diyhouse

@stephenw10 Many Tx for the feedback Stephen,..
I have tried to do some more 'searching',.. for events,.. have tried 'vi ppp.log' in ssh window,.. but not enough privs.. and using the file edit function, causes a php crash,..
So all I can probably do for now is wait for some more events,. and pull the associated logs as and when,. unless you have any other suggestions..
Also thinking,.. I did notice the re-connection stuff happens a while after the actual WAN looses connectivity ( obviously.. ) ,.. could it be I did not go back far enough in the logs initially?
I have tried to go back to these logs,. but I guess they are archived now.. is there any way to pull these logs,.. USB stick and copy files,..
I can see this would blow holes in any security,.. so I'm guessing that's a no no...

stephenw10

You can copy off or download the compressed log files if they still exist. You have to be logged in to do that so there's no real security issue IMO.

I would have expected to see that LCP echo reply error in the logs we looked at earlier. That's usually pretty close in the logs. But I guess it's possible.

diyhouse

@stephenw10 Just looking at getting the log files off pfsense,.. and noticed log files are all the same date,.. so old logs have been cycled out,..
Only after the point when I increased log file size do I have events,...
Just waiting for the next log rotation,...

Nearly 2.5days of continuous running since last WAN reboot..

But did get this crash log today..

stephenw10

Hmm, yes that seems unrelated. Though odd, I've not seen that before. Is that the first time you've seen that.

diyhouse

@stephenw10
yes... (And now 2days 18hrs 44Mins...)

and the log files sizes as follows,.. I would have hoped they would have been rotated by now... as they are getting quite large, even for a text file..

stephenw10

Mmm, I would certainly expect that. The default log size is 512KB. Did you change it to something much larger?

Having said that perhaps Openreach finally realised there was a problem and fixed it. Whenever I've had issues it was always a failing line card upstream.

diyhouse

@stephenw10 said in WAN periodically Rebooting:

Yes,.. to 2000000000 bytes... like 2gig..
I have now dropped it a power of 10,.. to 200,000,000 bytes...

I to was wondering if BT had got wise to my troubles and changed something upstream of my modem...
But we shall see..

I will leave the high logging in place for now... ( lets see if I can get to 10days...) then I will revert back,.. and see what happens.

Funny,.. things may have changed since I contacted BT,.. for account and passwd,. maybe an issue was raised,.. and something changed,.. but who knows..
I cat 'top' in a shell.. and see it is busy compressing,..

@diyhouse
One question I have,.. whilst in 'limbo'... the logs generated, have lots of the following;

Aug 25 09:22:30	ppp	67004	[wan] OUT util: total 29% 12% 61% 36% 6% 29% 27%
Aug 25 09:22:30	ppp	67004	[wan] IN util: total 625% 21% 2280% 1205% 108% 22% 111%

Are you able to spread any light on what the % values mean,...
Many tx
uptime currently running at 6d 18hrs

stephenw10

Not really. I've never tried turning up the logs to 11 like that before.

Edit: Appears to be the calculated bandwidth utilization:
https://sourceforge.net/p/mpd/svn/HEAD/tree/tags/RELEASE_5_9/src/bund.c#l1620

Not sure how applicable that is to PPPoE. Clearly it isn't actually pushing > 2000% of the available upload!
