Resolution:

VM running SharePoint was using vNIC adapter type E100E. I upgrade to VMXNET 3. It has been three days and I haven’t seen the error on the SP server. 

(Error returned)

I think it runs too often.

Change the Feed Cache Repopulation Job and Feed Cache Repopulation job to run once an hour.

1. Start up SharePoint Central Administration
2. Click the Monitoring link on the left hand navigation bar
3. Click on Review job definitions under the Timer Jobsheading
4. In the Job Definitions screen click the Job History link that shows in the left hand navigation bar
5. In the Job History screen look at the rightmost View option
6. Change the View option from All to Failed Jobs
7. Locate the failure by time and message based on what you saw in your Windows Event logs (it should say something about Feed Cache Repopulation Job)
8. Click on the failed job to view and edit its properties
9. Instead of running the jobs every 5 minutes, change it to run once in an hour.

Will report back if the errors go away.
