WF-Workflows in permanent warning state (SCOM Management Pack)

Question

Hi,
We're starting to monitor a small Service Manager 2012 R2 installation with SCOM 2012 R2.
After all discoveries have ran we have a permanent Warning on the Management Server, this warnign relates to the WF Workflows
The Repeats above are from my resetting the health the monitor. If I leave this alone the alert just stays Yellow/warning.
I've done some research into this but have now hit a brick wall and would like some help.
All workflows in the Service manager Workflows/Status pane are in good health.
Investigating further
I found this SQL script to list failed workflows.
SELECT
Rules.RuleName,
Rules.Comment,
Rules.RuleCategory,
Rules.RuleEnabled,
[JobStatusView].Status,
[JobStatusView].TimeScheduled,
[JobStatusView].TimeStarted,
[JobStatusView].TimeFinished,
[JobStatusView].Output,
[JobStatusView].RunningAs,
[JobStatusView].SubmittedBy,
dbo.MySubscriptions.LastModified,
dbo.MySubscriptions.UserSID as LastModifiedBy,
GETUTCDATE() as CurrentTime
FROM dbo.WindowsWorkflowTaskJobStatus
LEFT OUTER JOIN dbo.JobStatusView ON dbo.[JobStatusView].[BatchId] = dbo.[WindowsWorkflowTaskJobStatus].[BatchId]
LEFT OUTER JOIN dbo.MySubscriptions ON dbo.[WindowsWorkflowTaskJobStatus].[RuleId] = dbo.[MySubscriptions].[RuleEntityId]
LEFT OUTER JOIN dbo.BaseManagedEntity ON dbo.WindowsWorkflowTaskJobStatus.BaseManagedEntityId = dbo.BaseManagedEntity.BaseManagedEntityId
LEFT OUTER JOIN dbo.Rules on dbo.WindowsWorkflowTaskJobStatus.RuleId = dbo.Rules.RuleId
WHERE (( dbo.[WindowsWorkflowTaskJobStatus].[Processed] IS NULL AND
( (dbo.[WindowsWorkflowTaskJobStatus].[ErrorMessage] IS NOT NULL)
OR (dbo.[JobStatusView].Status = 3)
OR ((dbo.[JobStatusView].Status = 0
OR dbo.[JobStatusView].Status = 1)
AND (DATEDIFF(MINUTE, dbo.[JobStatusView].TimeScheduled, GETUTCDATE()) >= 25) )
OR( dbo.[JobStatusView].Status = 2) OR( dbo.[JobStatusView].Status is NULL) ) ))
The output of which is 
Our Exchange connector appears healthy, it's certainly processing email and no errors relating to it appear in the Operations Manager event log on the SCSM workflow/Management server.
As for MonitoringHostKeepAlive any ideas how to troubleshoot this? Again I see no errors and Service manager appears to be fully functioning.
All help gratefully recieved.

This one is bugging me too.
Am tempted to remove the Microsoft.SystemCenter.MonitoringHostKeepAlive management pack:
