Resolution

* the code 143 sent to the java process of the control node means that the cn has received a signal 15 (SIGTERM).

* this error triggered the stop of Integrator and the trading engine node

* to resolve the problem, find out why a SIGTERM was sent to the control node. It can be several reason like a Windows logoff or restart, or any intrusive external application (virus scan, porter scan, backup application ...).

* on widows, the Windows event might help. on Linux or UNIX, you can involve the system administrator
