• 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.

Issue Mailman3, cpu near 100% all the time

Hello,

I have a new plesk server with Debian 12.5, I installed mailman3 and I migrated a web who worked with mailman2. The domain have 40 lists more or less. As a result of this, cpu usage of the server is nearly 100% all the time with the proccess list of phyton causing this. It is impossible to access to the mailing list tab (too slow) and I have to restart the server a couple of times the load went crazy.

This is normal? Anyone knows why this or how to fix it?

Anyone used any other softwer of mailing list in case we have to uninstall mailman3?

Thank you very much
