This sounds like a bug. ODL is an opensource project with an active community and you will get a better response there than on stackoverflow.
I suggest that you retry using the helium release http://www.opendaylight.org/software and report it on https://bugs.opendaylight.org/ in the controller project. You will need to register.
There is not enough information here to investigate so when you write the bug report please provide:
- Software build used:
Needed for quick turn-around of ‘probably fixed’ issues
- Environment used:
To diagnose potential environment problems:
- Any customization outside of project-wide baseline
To understand deviations, helps prioritizing ‘currently unsupported’ issues
- Description of steps taken:
Needed for reproduction, helps finding ‘you are doing it wrong’ issues, here you need to describe the API call used
- Description of expected result:
E.g. what the reporter thinks should happen, helps finding ‘not-a-bug’ and architecture/design issues
- Description of actual result:
E.g. what actually happened
- Reasonable amount of logs
