• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is 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.

mmap cache can't open

General question - I've seen some of these errors lately loosely scattered around different servers.

[Mon Dec 1 21:08:20 2008] [warn-phpd] mmap cache can't open /var/www/vhosts/domain.com/httpdocs/file.php - Permission denied (pid 7831)

Does that just mean that the file doesnt have enough permission to be executed?

Im not terribly familiar with the mmap error messages, google didnt help much either. Does anyone know what this really means and what causes it?
