Dear forum,I've not been familiar with the lsof -p command until yesterday, and I just discovered one of our servers being extremely slow through a MySQL and a DA process. I'm not sure how to read everything, but I concluded that the 2000 or so open files going on in the background with MySQL is what it's supposed to do, but what's going on with the number of open files going on with DirectAdmin? And perhaps that'll explain why MySQL has its hands full with so much of its processing power being blasted upon.Edit: It's not done backing up all of the users yet, which explains why DA is still accessing those files. However, it's not usually taking this long. There's something else going on, and my top command does not reveal where most of the resources go in exactly, other than just... being there, being high. Yesterday I've interrupted the backups by rebooting, which obviously failed all pending backups. This, however, did not solve the root of all problems: high resource usage, which is still being carried over to today.

Most certainly not.
Depends on what php mode you use. But if you use mod_php than this could be the case, however in that case you should use mod_ruid2 for protection.
When using php-fpm normally 777 is almost never needed anymore.
They should just be 755.

That may point to some issue in the .htaccess file.

I know about the RFC, but is this customisable?
Outgoing mail: SMTPS mail.example.com 465 SSL/TLS

Like Gmail has?
Port for SSL: 465
Port for TLS/STARTTLS: 587

Because more and more systems are not using 465 anymore, even the biggest Dutch ISP (Ziggo) is not advertising with it anymoer. And as you can see Gmail only uses SSL on this, not TLS which is a more mode SSL protocol.
Also hotmail is using starttls on port 587 and not advertising 465 anymore.

I think some might appreciate a customisable option for this if possible.

yesterday I brought a VPS license But the resource limit not working. I can't find the resource limit in the DirectAdmin admin panel. Need help

You can adjust the limits at the DirectAdmin reseseller or user account at the modify pagina near the save button
