Issue Plesk not start after to error with autoresponder and reboot

[Maxwell Banks]

Hi!
Today my server consume all memory and cpu and I restar from vmware vcenter.

After to reboot plesk not start and redirect to repair kit.
At repair kit appear mariadb and sw-engine.service stoped.

I restart these services and appear a login page but never access to plesk and all web servers are down.

The versioon is 17.8.11 running at centos 7

Please I need some help to continue...

I found a bug about error with autoresponder, maybe the problem was when autoupdating? Is convenience try update?

I dont have backup, I need backup all data, but from terminl exist way to backup?

And what is the next step? How to can reactivate my panel?

Thanks!!!!
