Changed from error to warn in the case if the application does not contain *-sdf.xml/*-sla.xml file. Status check was added before processing response from SDF/ SLA servers for deploy/undeploy cases in 10.1.1.1
Another symptom of this may be that the SLA processing is affected and the SLA Widget is delayed in being updated. All items submitted from the time of the mass update did not show an sla status until after IIS had been restarted and overnight.
