I am using a new IBM Risc Netfinity system with pc clients. The network is Ethernet cards on the pc (tcp/ip) connected to a switch,10/100 and of course samba. When processing large print jobs on a pc, the program that is running (cobol) will error out. This error states that the program can no longer be found. The error is not on the file that is to be printed or will be printed. If I do a smaller date range on the print pgm. the program will run. With the same data (but moved to a different platform) I will do the above on a SCO Unix server and the programs will run well. The program runs in both cases about three or four minutes (this does not show signs of being timed out). I would appreciate any help. Bruce Garcia Aurora Software, Inc.
