Several of my reports deployed on Crystal Reports Server 2008 server fails everyday with the following error.
Error in File ~tmp121c5dc747685036.rpt: Invalid argument for database.
The error is not consistent, if report A fails today, it is Report B the next day. When I reschedule the reports, they run just fine. They fail only when the daily schedules run at 2:00 AM in the morning. 100 + reports are run at this time and some of the reports that fail run many times with different parameters. Is this error due to scheduling reports many times or is it something else? Appreciate any help with this.
