Connections can be refused either because the licensed connection limit has been exceeded, all the threads for a port are in use, no sdaemons are available, or Janus could not get the virtual storage for the required buffers on an <var>[[ALLOCC (JANUS DEFINE parameter)\|ALLOCC]]</var> port. Ideally, this number should be zero.
