• 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.

sw-cp-server does not maintain the pidfile /var/run/sw-cp-server.pid

Hi there,

From time time we observe the following phenomenon. Am I the only one?

Plesk nginx front-end (sw-cp-server) is running perfectly and listening on port 8443 but the pidfile (/var/run/sw-cp-server.pid) is missing or corresponds to a non-existing process (probably a previous encarnation).

This creates false watchdog alarms and inhibits any changes in Plesk front-end config (e.g. changing TLS certificate) becase a service sw-cp-service stop doesn't kill the process and the socket is already taken.

The only way to come back from this situation is manually killing the actual sw-cp-server process (easy to find through ps or netstat), actually kill it for a second time (the listener is taken over by another process) and start the process with the service command.

The server has not gone through any high load scenario.

Is there a way to fix this?
