When deploying many VDBs, some of the vdbs won't activate.

I want to deploy 22 VDBs, but only 11 VDBs are set to ACTIVE state.

This problem is random. It seems that it depends on the platform.
All VDBs are set to ACTIVE state on my machine, but only a part of the VDBs are activated in the lab (RHEL 6.5 x64).

Restart doesn't fix the problem.

Log is in the attachment.
