Openbase_dir error / proxy_fcgi:error

nu01 · March 30, 2025, 5:03pm

Of late, since 2 weeks, my system crashes due to the error mentioned in the logs. First the site crashes and then my server crashes.

Debian 12 Bookworm / PHP-FPM 8.2 / Apache2 / NGINX
Manual installation via zip: 2025-01-26.

Logs here.

I have removed duplicate entries, as this was repeated for 15K lines.

I have searched a lot, but not sure what file should this be edited or how can I fix this.

FYI: This is happening every 2 hours now.

I have gone through every possible solution on the net and here, but not sure what can I do to stop it. Only option is to reboot system, and then the site works again.

I have raised it with RSSBridge as well here.

nu01 · March 31, 2025, 1:59pm

Anyone able to assit please? All the php inis have open base dir as commented out. So not sure what I need to do here.

Seems that your app requires read access to /etc/mime.types but if you want to add access you should give access to /etc/ that in my opinion is risky.

open_basedir directive is generated from PHP templates /usr/local/hestia/data/templates/web/php-fpm/ so if you are using template PHP-8_3.tpl

cd /usr/local/hestia/data/templates/web/php-fpm/
cp PHP-8_3.tpl etc-PHP-8_3.tpl

And modify:

php_admin_value[open_basedir] = /home/%user%/.composer:/home/%user%/web/%domain%/public_html:/home/%user%/web/%domain%/private:/home/%user%/web/%domain%/public_shtml:/home/%user%/tmp:/tmp:/var/www/html:/bin:/usr/bin:/usr/local/bin:/usr/share:/opt

to:

php_admin_value[open_basedir] = /etc:/home/%user%/.composer:/home/%user%/web/%domain%/public_html:/home/%user%/web/%domain%/private:/home/%user%/web/%domain%/public_shtml:/home/%user%/tmp:/tmp:/var/www/html:/bin:/usr/bin:/usr/local/bin:/usr/share:/opt

Save the template and now assign the new etc-PHP-8_3 template to your site.

nu01 · March 31, 2025, 3:16pm

Thanks. I am trying, but it throws the error Error: etc-PHP-8.3 backend template doesn't exist

sahsanu · March 31, 2025, 3:18pm

Sorry, my bad, I used the wrong template name (I’ve corrected it in above post).

cp PHP-8_3.tpl etc-PHP-8_3.tpl

nu01 · March 31, 2025, 3:24pm

Thanks, but should it not be tpl only? Reason, when I used tlp, it kept throwing the error, but when I changed it to tpl it is now trying to apply it. Will time out for the same weird reason it always times out, but will get applied in the backend.

BTW, is there a manual way to edit some file somewhere to apply these templates etc? UI causes the apache2 restart failure every time a custom template is used.

Although now PHP-FPM fails to restart.
Checking the logs now.

Edit: System reboot started the php-fpm now.

sahsanu · March 31, 2025, 3:25pm

Yes, sorry again

nu01 · March 31, 2025, 3:26pm

Hey. Do not say sorry mate. You help more than you can imagine.

But if you can say if there is a manual way to apply these templates, I would be more merrier.

sahsanu · March 31, 2025, 3:31pm

 v-change-web-domain-backend-tpl YourUser YourDomain etc-PHP-8_3 yes

nu01 · March 31, 2025, 4:01pm

Thanks mate. Sorry for the late response. Was away, having my food.

This is what keeps happening now, and PHP-fpm crashes every now and then.

I do have all other sites also running the same PHP FPM version.

All looks good, I see no obvious problem.

nu01 · April 1, 2025, 12:14pm

For now. In sometime my system will crash again, and all those running this phpversion will stop working.

I have huge data, so I am skeptical to format and do a clean installation.

sahsanu · April 1, 2025, 2:20pm

You should review the logs to know what’s happening when php crashes:

/var/log/php8.3-fpm.log
/var/log/apache2/error.log
/var/log/apache2/domains/YourDomain.error.log
/var/log/nginx/error.log
/var/log/nginx/domains/YourDomain.error.log

You could also tune the pool conf for your domain or domains, also maybe you should raise the limit of open files used by php-fpm.

nu01 · April 1, 2025, 4:28pm

I have updated my pool and workers limits. Also, moved this rssbridge out to another php version (8.2). Hopefully this will help. There were too many in error logs. I disabled those bridges as well.

nu01 · April 2, 2025, 10:55am

I told you. Happened again. All sites stopped working as PHPFPM number of workers and RAM got overloaded. Trouble is the PHPFPM although auto restarts in this situation, the apache2 does not, nor does nginx.
Confused and feeling out of galaxy now.
Other than RSSBridge, NextCloud is also causing this it seems.

Biggest issue is, when it happens. Either I am asleep, or am at work and in both these situations I have no way of doing anything that time.
