When running an application which uses CCINAMPU, if an error occurs when starting either the client or the server components, and the error status indicates that the system was too busy to create a new pipe, then it is most likely that the access permission set in the service location directory - for default service locations /usr/spool/uucppublic - is incorrect. The permission must be set to 777 for CCINAMPU to function correctly for all users at all times.
