Hi, There is a possibility that a activated cartridge instance get relaunched when it is identified as a faulty member. When cartridge agent running inside the instance fail to sends it's statistics to CEP for 1min, Stratos marks the instance as a faulty members. The the instance will be terminated and relaunch another instance in the same partition.
Anyway should have a look to see the what causes the relaunch. Touched, not typed. Erroneous words are a feature, not a typo.
