21.1 Unable to Stop the eMTool Services

When running the command serviceStop -n{service}, where {service} is one of the services (libsasl.so, libncpengine.so, libhttpstk.so, or libdsloader.so), the following error occurs:

Service {service} could not be stopped, Error : -660

This is not an error. You cannot stop these processes (specifically libsasl.so, libncpengine.so, libhttpstk.so, and libdsloader.so), because there are other modules dependent on them.
