SIM 5.2 SSH Problems

[stefano colombo_1]

HI ,
I've upgraded from SIM 5.1 to 5.2 .
Since then I'm experiencing problem with jobs.
For example I'm trying to reregister servers as VM hosts but the command fails with the following error

The VMM agent cannot be connected or is locked to another service. Install the VMM agent or unregister it from the other CMS.

I've tried :
- configure repair agent ( no luck)
- mxagentconfig on the cms ( no luck )
- remove the server1 from cms , add it back , configure agent ..

nothing had effect on the issue
Has anyone an Idea on how to solve it ?
thanks
