That is cloudstack. But then I thought of it; I asked someone on the cloudstack stand at Dusseldorf; and the 4.0 was upgraded to 4.3. It seems that there was something wrong with the packages there: the old 4.0 manager/agents were not properly shutdown before they were replaced by the cloudstack version of the packages (the previous were called cloud). It might be this that you are noticing. I killed the processes manually and restarted the cloudstack application.
