> Components: bsp
> Affects Versions: 0.3.0
> Reporter: Edward J. Yoon

> Task t = ((LaunchTaskAction) action).getTask();
> int peerPort = (Constants.DEFAULT_PEER_PORT + i);
> assignedPeerNames.put(t.getTaskID(), peerPort);
> i++;
> }
> {code}
> Increasing naively the number of port will potentially cause "already in use" error. We may need to find next available port.
