The first symptom detected by Robot suites is constant 404 on jolokia URL. This Carbon bug does not happen in only jobs. This weekend it hit both Netconf and Controller jobs, previously this was only seen once [0].

Karaf.log for this Bug contains reports on runtime-generated-mapping not finishing, followed by "giving up" from AbstractDataStore:

2017-02-26 04:02:37,092 | WARN | saction-32-34'}} | DeadlockMonitor | 131 - org.opendaylight.controller.config-manager - 0.6.0.SNAPSHOT | ModuleIdentifier

{factoryName='runtime-generated-mapping', instanceName='runtime-mapping-singleton'}

did not finish after 169982 ms
2017-02-26 04:02:40,606 | ERROR | Event Dispatcher | AbstractDataStore | 216 - org.opendaylight.controller.sal-distributed-datastore - 1.5.0.SNAPSHOT | Shard leaders failed to settle in 90 seconds, giving up

Possibly this is just a performance Bug (startup taking longer than expected), but when the restart succeeds [1], the instance is created in around 10 seconds. Most probably some ODL project tends to make WaitingServiceTracker not find BindingToNormalizedNodeCodec.
