Hi I am using datasockets to connect to a third party program which drives a DAQ system (Fluke DAQ with a 2680 system). That program comes with an OPC server which publishes the measurement data. With Labview I can subscribe to this data using datasockets, and this runs fine for most of the time. However, I occassionally get problems where the OPC server of the third party program seems to generate an error (it mentions it can not write data to memory and then crashes). The Labview program which contains the datasocket connections hereafter also crashes (If I build an application only the application crashes, if I run it from the Labview development environment, the complete development environment crashes).
I tried with datasocket connections via the front panel as well as with connections programmatically entered. Both seem to give the same result. Anybody an idea from which this instability results or any suggestions which could improve stability ? I understand that my third party program may be the original cause of the problem, but I do not understand why Labview is crashing as it is in fact only "listening" to the results published. Thanks Martien
