I have no dovecot logrotate file. Logs are in maillog aggregated with postfix. I checked cron and I didn't find any suspected jobs which can reload dovecot. Here is my logrotate.d files:

I have dovecot logs in maillog but it's detail.

Memory is not an issue. I have 20-30 GB free on this server. I forgot write about it before. I have found something more in logs:

It didn't help. I have very high client limit now - 4000.

I made mail repair without success. Problem is still exists.

Unfortunately problem comes back. This is what I found in maillog:

I set default_vsz_limit to 1G. On status I didn't see any interesting entries.

Every day I receive alerts about imap server problem. Dovecot stops work for 2-3 minutes. In logs I have something like this: I don't know what is the problem source. Maybe too many connections etc.? Could you tell me how to debug this issue?

No errors in this log file. Today task manager have lower load about 50%. Maybe something big was to do.

Plesk task manager takes 100% all the time. I wonder how can I find why it's do that? psaadm 3358139 111 0.2 3083652 177736 ? Ssl 10:44 4:55 /usr/libexec/plesk-task-manager --config /usr/local/psa/admin/conf/task-manager.yml --data /var/lib/plesk/task-manager In longtask table I...

This is great answer. :) Conclusion is better to run many smaller servers (or VM) than a few big.

I would like to ask how many customers can I host on one server without issues. Let's assume that I have strong hardware like Epyc, much RAM and nvme storage. In this case can I host 100, 500, 1000 or more typical subscriptions with mail service? I'm wondering how much time server will do...

I have several servers with Plesk. When I reach about 200 subscriptions and around 1 TB of data backup process takes a long time like 10-15 hours. I wonder how to optimize backups? All Plesk installations run on Proxmox KVM VM. Servers are different configs but quite good like AMD Epyc or Xeon...

Version 18.0.59 fixed this issue.

No. I was greped all logs by new domain name. I think serial is not a problem. It's looks like Slave DNS extension don't send rndc query. On slaves server I don't see any sign about new domain. If my rndc key was wrong I won't update zone manually. It's right?
