Better fixing for journal parsing

With the latest approach, from time to time, the AUM tests does not catch the upgrade and reports the error. This happens due to the fact that the upgrade is done right after the restart and cursor is updated in the loop.

To avoid the issue detect change the way AUM crashed are caught taking into account the number of restarts in the log.
