  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Alekseya, judging by your screenshots, you have only about 2.3 Gb of memory consumed by applications. This is not that bad.

Here's what the numbers in top/free/Health monitor mean, if you need clarification.

Total - your total (physical) RAM (excluding a small bit that the kernel permanently reserves for itself at startup).
Used - total memory in use by OS.
Free - memory not in use at all.

Total = Used + Free.

Buffers/Cached/Shared - this shows memory usage by OS itself for specific purposes. Values are included in the 'Used' value. This memory is usually used by OS to speed things up and can be claimed by applications on demand.

Therefore to see "real" memory usage you should calculate (Used - (Buffers + Cached + Shared)). Alternatively call 'free' command, which does it for you in the '-/+ buffers/cache' output line.

Also, it's worth to note that "MEM" field in 'top' output is "a task's currently used share of available physical memory" or a so called resident set size. "VIRT" or virtual image size is usually more representative in terms of overall memory consumption.
