SSO Upgrade Error

Hi!

We have:

1. 2 SSO in multisite mode

2. 2 vCenter Server 5.1.0b

3. Linked Mode

4. SRM

Everything works perfectly, no any mistakes.

In attempt to execute updating SSO to build vCenter Server 5.1 Update 1a (1123966) - immediately error and emergency end of updating of SSO.

Log in attach

Ideas?

Thanks

Alex
