Problem Note 46765: Copy fails because of "nc: Address already in use" error
 |  |  |  |
During SAS® High Performance Markdown Optimization batch processing, the %tkmi_job_ro est_start_service task or copyDataToCaptains_service task might fail with the following error in the HiPerfMerchIntelGridSv.log file:
2012-05-27 16:08:50,089 [pool-9-thread-1] ERROR - Copy failed for <your_grid_node_name> using <sashome>/SASHighPerformanceMerchandiseIntelligenceServer/4.3/Scripts/Captain/cp2captain.sh 1/<partitoin_id> <data_mart_path> <miuser>/all-common-files.tar.gz /home/<miuser>/dm nocache b nc <data_mart_path> <grid_server_name> <port> pigz2 <sashome>/SASHighPerformanceMerchandiseIntelligenceServer/4.3/Scripts/Captain java.lang.Exception: nc: Address already in use
This error occurs because the port that is used for copying files is in use. Log on to the server that is identified as the <your_grid_node_name> in the error message, and issue this command:
"font-family:monospace;">netstat -tcp -an | grep <port>
This output provides you with the process ID of the process that is using the port. You can then use the ps command to determine the command using the port. Once you know about the conflicting process, you can determine whether it is a legitimate process that needs to complete, or it is something that you can terminate.
