A system call has failed. The sqlexecd daemon or database server cannot access the network port that is specified by the servicename in the sqlhosts file. This situation might occur because the network port is already in use by another sqlexecd, database server, or other application. Use a different servicename on the command line (prior to Version 6.0) or in the sqlhosts file (beginning with Version 6.0). Contact your system administrator for assistance.
