Hey there! It's hard to recommend much for this situation without some additional details. Do you see that chkservd was killing this process? This would show up in /var/log/chkservd.log on the system.

After restarting dovecot you can use a tool like "top" to see the amount of resources it is using.

Thanks for the details. The size of that account is going to be challenging for dovecot to read properly, as other users have experienced similar issues:


It might be best to submit a ticket to our team to see if there is anything else that can be done on the server side to lower the resource usage. If you do decide to submit a ticket, please post the number here so I can follow along and keep this thread updated.
