Webi Schedules fails intermittently

Dear Experts,

We have observed that intermittently the scheduled webi reports fails with an error "

Objectfailed to run due to an error while processing on theJobServer". When checked in the event logs it displayed that "The scheduler component failed the object identified by XXXXXX. The job associated with the object was unresponsive"

When given a Run now to the reports, the instance is successful and no issue is observed.

Version: SAP BI 4.1 SP05 , Clustered, Windows 2012 R2

Please advice.

Regards,

Diego.
