Protocol: SFTP SSH-2
Interface: Norton Commander

When it take place:
- last month on the one hosting (on the other hosting - that's all right)
- hosting allow to create 5 session at one time
- update version - don't anything change
- erorr appear at regular intervals (regular by the hosting timing possible) - nearly 5 minutes: if I connecting passing some time (from several second to five minutes) -> conection close -> reconnecting at once -> conection close after 5 minutes...
