IIRC this might be automatically set from FD's in the system, but if not you may need to set this to probably 80% of your FD limit frlom the systemd service tunings you have provided. Hope that helps, -- Sincerely, William Brown Senior Software Engineer, Identity and Access Management SUSE Labs, Australia _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure Thanks William.
