Hello Mayur,
I usually see this happens on scheduled reports because someone changed their network or Active Directory password. When they change it, the trusted credentials Cognos uses to run schedules in the background stop working. If this is the case then have the person who owns the scheduled report log into Cognos, go to their Profile icon Profile and settings Profile tab. Then scroll down to Advanced options, find Credentials, and click Renew.
In the meantime, could you try restarting both the Cognos services and the Oracle Content Store database to see if that clears it up?
Thank you,
Abbas
