Issue with bes 5.0.1 bundle 5-cannot open BAS console

Hi,
I am receiving this:
Even id 7031 "blackberry administration service-application server service terminated unexpectedly.
It has done this 1 time (s). The following corrective action will be taken in 60000 milliseconds. Restart the service"
I am interrupted with this many times a day. Where users receiving their e-mails, then I can’t make any step until understand about the problem.
I already have restarted both the blackberry administration service-application server and native code container services running 5.0.1 bundle 5.
I have also searched over internet for solution but disheartened. I am really needing help.
Thanks a lot
