Thanks, Dmitri. One of the servers had - and still has - disabled Windows Defender. I'll check anothers. Most of the time process last up to 1 minute - anyway it is too long - but there are days it is up to 1 hour.

You think I should check terminals?

Noway. Fortunatelly my clients have patience...
