The symptoms are:
- Possibly re-running the jobs will execute successfully.
- The issue is intermittent.
- The issue does not seem to occur for smaller data result sets.
The cause is due to the following NIC card settings for the machine hosting SQL Server. The setting is the Chimney Offload State. Contact Microsoft Support if you need assistance with this setting.
With this setting set to enabled, this behavior may occur.
Resolving the problem
To resolve the problem, change the Chimney Offload State NIC setting to disabled.
