It is important that only one set of system tests for each package is running at any given time. (This can probably be fixed.) You can run a set of system tests for EngModel and GlastRelease simultaneously, but you cannot run two sets for different GlastRelease versions, because the tests will try to store the output files in the same working directory. After you start the system tests it is usually a good idea to look at the file testerr (in the same directory that you ran from). We fairly often get a sporadic error when connecting to the Oracle database. If this happens, you should just kill the jobs with bkill 0 and start them again.
