error when submitting timesheet.

[GG]

When I try to submit timesheet, I got the following error:

Error summary/areas:
Action canceled because there was a Server Event Service problem.
GeneralActionCanceledBecauseServerEventServiceProblem
Queue
GeneralQueueJobFailed
Error details:

</class>

I tried delete the timesheet and submit again, it gives the same error.
Doesn't anyone know why?

Thanks
