This is visible in karaf.log [0] as the following:
2017-05-14 06:11:38,008 | WARN | saction-65-67'}} | DeadlockMonitor | 122 - org.opendaylight.controller.config-manager - 0.6.0.Carbon | ModuleIdentifier

{factoryName='rest-connector-impl', instanceName='rest-connector-default-impl'}

did not finish after 64975 ms

This affects CSIT results. Specifically, calls to Jolokia work correctly, but restconf calls such as remove-shard-replica result in status 401 [1].

This become visible after suites stopped waiting for /restconf/modules due to AAA-130.
