Hello, what @[deleted] said is quite possible about auto-cron, because Auto-cron: "Enables periodic email fetching using an internal task manager triggered by Agents' activity."It might be that your cron, which you have set up, e.g., to fetch e-mail every minute or less fetches the mail at the same time as auto-cron triggers via your or someones activity and if you have a lot of agents, it makes it even more possible.Try to disable auto-cron and see if that helps, you do not really need to use auto-cron if you have cron script running every minute or so, it won't make it a lot faster :)
