LabVIEW client receive ghost events when DS is stoped
|

---|---|
I am observing a rather strange behavior. My LV2020 on the Win 10 client subscribes to the data_change_event for sys/tg_test/1/ulong64_scalar. The timeout is set to 1 second. When Test Ds is running, everything works as expected. But when I stop the DS, at some point my client receives a ghost event with timeout = false. ![]() How to reproduce this:
Can somebody explain this behavior? Workaround is to check error code == 0 in the attribute raw data cluster. |
