Pinned topic An internal error occurred during: "Model Synchronization Job"

‏2010-08-09T06:31:57Z |
Hello,

recently in RSA 7.5.5.1 appeared the error message
An internal error occurred during: "Model Synchronization Job".
java.lang.NullPointerException

What may be the reason for this error?
On which circumstances can it occur?
How can it be avoided?

    Do you have the full stacktrace of the nullpointer. Refer to your workspace using a file system browser, and open the .log file inside of your workspace and look for the NPE stacktrace, that can help us to find why the NPE has occured.

      That's the extract of the corresponding workspace log:

      No further stacktrace elements appear after this error entry.
      HTH for diagnosis.

        Any news on this?

        The same happens to me in RAD8 in different installations on Win7 x64.

          Hello, are you seeing the same stack trace in the log? Could you include the stack trace here?
