Hi,
We have been experiencing several of these errors in the hpc head node server's event log.
An unexpected exception occurred. For more information about this exception, see the Details tab.

The scheduler was unable to commit a transaction.
An unexpected exception occurred. For more information about this exception, see the Details tab.
Additional data:
The operation could not be completed because the affected object is already in use by the scheduler. Please try again later.
after these errors - the task would be marked as failed and the message would be
an unexpected exception occurred while validating the job. Please try to submitting the job later. If the problem persists, please contact your system administrator or check the HPC server event log for more details
Do you know why this is happening? We are using HPC 2012 R2 update 4, with an external sql database. Do you have any other troubleshooting steps that we can perform. The task runs fine when it is requeued.
Thanks!!
