Problem with Virtualmin
A lot of processes are created with the name:/usr/bin/perl /usr/share/webmin/miniserv.pl /etc/webmin/miniserv.conf
When the value of 330-370 running processes is reached, Webmin is completely disabled in the system, and Virtualmin is only helped by restarting from SSH.
But after 5-10 minutes, the system freezes again from a large number of processes: /usr/bin/perl /usr/share/webmin/miniserv.pl /etc/webmin/miniserv.conf
Is this a new install of Virtualmin (you have posted in the forums for the first time, so I ask) or has this problem emerged in an old install of Virtualmin which has been running normally for a time?
What has triggered this? Have you enabled a feature in Virtualmin / Webmin which will cause it to spawn many processes? Do you see lots of unexpected entries in your Scheduled Cron Jobs screen?
All I can say for certain is that Virtualmin comes with sensible defaults and the behaviour you describe can only be caused by your having set a parameter which causes Virtualmin / Webmin to do lots of things repeatedly in the background: managing messages in your mailboxes, for example.
I get that: miniserv.pl is Virtualmin / Webmin so it is clear that the resources are not being consumed by any other script.
All questions in my previous message pertain to settings and configuration parametres that you may have applied. After installing Virtualmin, have you changed or tweaked any settings which may trigger multiple processes?
Additionally, if you care to answer each question that I have posted in my previous message, it will help me and others in the community help you more effectively.
Your original statement quoted above does not hold true if you have removed MySQL 8.0 and added MariaDB along with several versions of php 7.0, 7.1, 7.4.

There was an issue with Webmin 1.960 or 1.961 which created a lot of collectinfo.pl processes. And that is now fixed with Webmin 1.962

Just check whether your issues is also related to that.
After upgrading: Apache 2-issues a lot of its own processes, despite the fact that the activity is only on one site. (reaches up to 500 Apache 2 processes) Very large number of processes /usr/bin/perl /usr/share/webmin/miniserv.pl /etc/webmin/miniserv. conf - which really slows down Virtualmin.
The question is not about the password and its change. The problem is that phpmyadmin works with errors. And I didn’t find a solution to these errors. When entering the user’s username and password, everything works fine, but these errors are a little annoying for me.
Invision Community Suite talks about errors but not critical errors. Installed MySQL server MariaDB 10.5. before installing virtualmin (only used webmin), there were no such errors. If you paid attention to the screenshots, the user’s login field is duplicated in phpmyadmin on the login page. There are suspicions that these are php errors but neither as not MySql server.
