backup exec job engine service not responding

I am using backup exec 2012 SP4

I have issue with the backup exec job engine service it is not responding in week

• Repair the database / failed still issue same
• Enable the all the logs open a case with ADV
• Symantec BE team have review the logs
• Upgrade the version from sp3 to sp4
• Still issue same
• We have also  run the STSINV tool for check the ost media / as per Symantec support there is no issue with the dedeuplicaiton folder

Is there is any workaround to resolve the issue
