  Hello @MrMatt, I moved this post to it's own thread, as the previous thread related to general information about the Solr service. Could you verify if this system uses CloudLinux? We have an internal case (CPANEL-12782) related to the cPanel OOM functionality sending notifications for cgroups (this isn't supposed to happen). This can lead to the tailwatchd process consuming a large amount of CPU due to the excessive amount of notifications. Thank you.

  Hello, To update, the issue associated with CPANEL-12782 is fixed with cPanel 64.0.18: Fixed case CPANEL-12782: Avoid sending OOM notifications for cgroups. Thank you.
