Have any of you experience this annoying, frustrating and intermittent SAS/AF problem ?
We are running a system to allow up to 6 concurrent users to key information into SAS datasets held on a IBM mainframe (running z/os 1.9, with a SAS version of 8.2). The keying is done via a PC sas session using SAS\CONNECT and Remote Library Services, with the data being displayed in SAS\AF panels. The system is prone to intermittent failures, which lead to the PC end freezing, or to a windows style message to the effect that SAS must close. On at least one such occasion, the SAS log showed the error message listed below. The failures are usually also accompanied by an EVENT ID 2401 message being sent to the windows event viewer.
