TITLE

After upgrading to Plesk 18.0.30 apache stops randomly.

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk Obsidian 18.0.30, Ubuntu 16.04.7 LTS, x64

PROBLEM DESCRIPTION

After upgrading Plesk 18.0.30 apache stops at random times 1h , 48h, 30min...
When graceful restart its checked apache stops more frequently.
When apache restart interval is low (1 min) stops more frequently , now its configure in 30 min.
Apache has stoped 4 times in last 24h.
Sometimes I've recibe the following message:

Code: 
Unable to generate the web server configuration file on the host <kinetica.mobi> because of the following errors:

Template_Exception: Can not restart web server:
file: /opt/psa/admin/plib/Service/Driver/Web/Server/Apache.php
line: 122
code: 0

Please resolve the errors in web server configuration templates and generate the file again.

I thinks this error occurs when apache has stoped yet.

STEPS TO REPRODUCE

Install Plesk 18.0.30

ACTUAL RESULT

Apache stops randomly

EXPECTED RESULT

Apache doesn't stops

ANY ADDITIONAL INFORMATION

Different Logs and apache status:

Hi, I've already run Plesk Webserver Configuration Troubleshooter and regenerate all files, no error.
Also run plesk repair web -v -y
I've rerun Plesk Webserver Configuration Troubleshooter I find a domain with error (expired yesterday) I've regenerated again and no error showed in the extension.
 
I have the same issue, plesk simply doesn't seem to be able to start apache for some reason. I can restart apache via command line and everything seems to work as normal, only Plesk can't start apache. It sure can stop it though.

I get the same error in the plesk repair tool, when trying to reboot apache in the Configuration Troubleshooter and when changing settings in the web sites. Always the "line 122" error since I updated Plesk to 18.0.30 on Ubuntu 16.04.
 
Cannot reproduce the issue.

Please provide the output of:

Thanks! - as an additional note, it appears to want to create mail templates for domains which do not have mail enabled. these then fail and therefore the issue.

Maybe this will be of help. Got the same issue with Debian 9.

Hi, if i click on reconfigure all configuration files in Plesk console and watch in shell for apache status if down, and manual start apache, the configuration is successfull. And the error is gone form me.

Get this error in /opt/psa/admin/logs/panel.log so maybe plesk is having a problem with restarting the webservice...

Code:

I have same issue.

After upgrading to Plesk 18.0.30, apache was unable to start because plesk failed while regenerating apache and nginx config files.

Here the error:

Can not restart web server:

I resolved temporally the issue (I thought) upgrading to last version of apache (apache2 2.4.29-1ubuntu4.14 (Ubuntu for bionic-updates by Ubuntu) and It started to work.

This morning, after creating a new domain, (a subdomain), apache begun to fail again, same error, because Plesk is unable to generate the apache and nginx config files of that new domain.

I resolved temporally the issue deleting the new domain and restarting the server.

Some minutes ago, after modifying an existing domain, nighmare start again.....

and what will this do? I executed and no output or response?
The problem is randomly showing up on domains with no email setting turned on. Domains that have been fine up to now. it appears to be around:

Thank you for the provided information. Those affected may try to workaround the issue by executing as root:

Bash: 
sed -i -e 's|^\(apache_status_linux_debian\)|_\1|g' /opt/psa/admin/sbin/pleskrc
Click to expand...

This indeed fixes the issue for me and allows Plesk to restart the apache server again.
 
I have the same issue... plesk thinks it cannot restart apache2 but using service apache2 start - starts it just fine...

After updating from 18.0.29 to 18.0.30 MU#1, I got the same issue as also listed in https://support.plesk.com/hc/en-us/article/115000469949?page=1.

This seems to solve the problem temporarily. It would of course be great if we get more details if there is anything else we should do. Also, the help article that I cited should quickly be updated.

FYI: the issue is confirmed as PPPM-12387 and will be fixed in 18.0.31. Until then, if you're affected, it is sufficient to use the provided workaround.

Does it only happen rarely? Otherwise, I guess this should rather be part of the next micro update?
