• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Resolved 503 Service Unavailable

Hi, yeah, thanks. If you read the earlier comments, you'll see someone already suggested that.

And? Have you tried to apply patched apache_control_adapter? Did it solve your initial issue?
 
Same problem here, even with the patched apache_control_adapter.

Plesk servers with a few domains are working fine.

Plesk servers with about 200 domains are having problems, it seems to make a graceful and then a restart.

Is it possible to have an uncompiled version of apache_control_adapter to adapt to our needs? Or make a version with a long timeout to be compatible with hosting providers with shared servers.
 
I solved the problem downgrading apache_control_adapter script to the version included in Plesk 12.5.

No more Apache restarts after graceful.
