SharePoint 2013 Search Administration Exceptions Filling Event Logs

After a patch cycle the Event log starts filling up on the web/app servers -

The following 6398 Timer errors start appearing every 10/30 minutes in the event viewer:

The Execute method of job definition Microsoft.Office.Server.Search.Administration.QueryClassificationDictionaryUpdateTimerJobDefinition (ID <GUID>) threw an exception. More information is included below.

Unable to locate Managed Metadata Proxy which is default keyword taxonomy for SSA <ID>

The Execute method of job definition Microsoft.Office.Server.Search.Administration.CustomDictionaryDeploymentJobDefinition (ID <GUID>) threw an exception. More information is included below.

Failed to run flow Microsoft.CustomDictionaryDeployment. Correlation Id: <ID>.

All of the search functions still work, so nothing actually seems to be malfunctioning, however having the event viewer constantly full of false positives could potentially create a situation where important events are missed, or it becomes unnecessarily difficult to find an event you're looking for.

There are several suggestions when searching online -

1. In the Managed Metadata Service Application, check "This service application is the default storage location for keywords" and "This service application is the default storage location for column specific term sets".
2. Give your search service account access to the Managed Metadata Service Application.
3. Re-run the configuration wizard on the servers one by one.
4. Reset the Index and do a full crawl.

None of these suggestions work if the Managed Metadata Service Application was never added or configured in the first place. Rather than adding an unnecessary service application, I opted to just disable the unneeded Timer jobs from the Central Administrator.

From the CA click on Monitoring, Check Job Status, then click Job History on the left side navigation.

From the View: drop down, select Failed Jobs.

This will bring up all of the failed Timer jobs. We're looking for the Query Classification Dictionary and Search Custom Dictionaries jobs.

Click on the job and click on the Job Title, and then click on Disable. Repeat for the second job.
