各位, 我用 virtual machine 成功安裝 sas enterprise miner 5.3 之後
卻不能成功運作, 系統說是未能connect to object spawner server
我去了 system 中嘗試用手動方式啟動它 卻失敗了

一運行 就彈出 sam.S249.ex.msg: A connection to server host hostA could not be established on port 8591. Either there is no server listening for connections or the server is too busy to accept any new connections. Make sure that the server has started and that the values provided for host and port are correct.

請問如何解決這個問題, 先謝各位了
