fatal error

[Kousy]

In a particular vi where i am using all DI/DO read/write & AI/AO read/write in timed loop, suddenly got a fatal internal error : objheap.cpp, line 579 LV7.1

what does it mean? & how to rectify? in design mode also i am not able to open it, says this error closes LV.

Hi Kousy,

I searched our database, and this is a known issue with LabVIEW 7.1 that has since been closed. It seems as though it does not consistently occur, but if you would like to attach your VI that exhibits this behavior, we can look into it further and see if we can find you a workaround.
