When using ProducerTemplate for execution of an ssh command (i.e. producerTemplate.requestBody("ssh://...", String.class)), 11 threads are being created, that are never killed. Any subsequent calls create new threads, eventually this exhausts memory and thread resources on the machine.
These threads are not being killed even when explicitly stopping the ProducerTemplate.
