503 Service Unavailable Error

@flipwalker what Linux is are you using? It matters. Typically fpm logs are found in /var/log/php-fpm/www-error.log I believe or very close to that path
-
@tom-elliott Ubuntu 16.04. In var/log/ I have a file php7.1-fpm.log, but there’s no php-fpm directory, and no www-error.log that I can find.
-
@tom-elliott Alright. Some progress. I found the step I missed. I assumed that fpm was default, but I see now that @george1421 had people follow his steps to get it installed. I’ve got it installed now and when I restarted apache and php as part of that process magically everything is working again. For the moment. But now I sit and watch computers image for the next 5+ hours to see if they start erroring again.
-
@flipwalker Just for clarity, can you confirm the steps you took to resolve (hopefully the issue)? I provided several steps here trying this and that to find a common thread.
-
@george1421 I originally didn’t follow your guide to install and activate fpm, I had assume it was default. Once I followed the guide(not without cursing and much looking up of VIM guides), and got it installed and activated my web interface came back up and my clients waiting to image started communicating with FOG again.
I’m still not 100% that it’s fixed or if the last step(restarting PHP and Apache) simply reset the problem and it’s going to reappear in a few hours. I’ve been watching it run for 45 mins or so now and it at least appears to be stable. But we’ll see if it completes overnight or not.
Just wish I had remote capability so I could monitor from home instead of having to come to the office.

@george1421 This particular machine is only servicing about 30 units with 4 distinct named users and currently reporting about 375MB free. Looking through its history over the past 2 years (reported through snmp), it historically has had anywhere from 350MB to 500MB free, depending on the day of the week. Truncating the userTracking table does make it happy for now. If you are loading that table with PHP on every request, the behavior does make a lot of sense.
@Tom-Elliott I completely understand that, and for this particular environment it is not an important feature. We have some other larger environments (250-ish) where the user tracking feature does get used from time to time (“Hey, was the account of student X used to log in yesterday?”), so It is something I check in my canary system.
@flipwalker The box I have is also Ubuntu 16.04. Check to see if your config file is in /etc/php/7.1/fpm/pool.d/.

Not sure if this is related I have an older post where my web ui stopped working but my error logs are just
non well formed numeric value encountered in /var/www/fog/status/bandwidth.php on line 109 and 110. -
Hi, it sounds like the same issue I have had.
My solusion was to remove the www.conf in the /etc/php-fpm.d directory.
this directory must contane one file only (fog.conf) -

this directory must contane one file only (fog.conf)FWIW, my instructions say to use fog.conf, the fog installer created the www.conf. So the fog installer owns www.conf and will be created each time the installer is run. You should remove the fog.conf file since that was hand created or you will have problems each time you upgrade fog.
-
@pijltje Hmm I don’t see that directory I am using Ubuntu (I know I know, first time fog when I have time I WILL switch been a pain honestly)
