Could you please specify if you are still encountering this error? Though we couldn't reproduce it, we can send you a test build with logging enabled to localize the error's cause.

Hello,

For the time being, we do not still encounter this error. We had some changes in our RAC configuration and setup and it seems that the problem went away.
