Okay, 

For your info and info of all Vserver  developers.

Right now our primary task is to CHANGE protocol of Vserver.
This is main task for 2.2 release.

Current protocol is weak from point of view error-resistance.
We going to use new protocol which should simply remove these STREAM ERRORs


-------------------
Another step we do in this regard is:

    Valentina put on protocol a lots of API methods.
    we name this as reach protocol.

Up to now this was manual work. We have found relatively easy way to
automate this. So we have big hope that 2.2 release will increase a lots
stability of Vserver protocol.

Except of above, new protocol solve other major tasks:
    the main is: ability to future extend commands and that old
    server and clients still are able work with newer server clients.
