Capture Failing

[DogOnWood]

I have 2 RT systems running Phar Lap 13.1, one with a 1033 PXI chassis and the other with a 1036, both are configured the same way slots 2-4 have PXI-6133's, slot 5 has a PXI-2536 and slot 6 has a PXI-7811R.

The system with the 1033 had been running well for the past several years, we decided to get the system with the 1036 up to the same level as the 1033,  now neither system is working......

to test the setup I'm using the demo VI " Voltage - Finite Input.vi"

using DAQmx 16.0.0 when I try to use the 6133's I run into issues, the one in slot 2 works as expected. slot 3  frequently fails to capture all requested data and is slow, and slot 4 will hang indefinitely.

This is on both systems! I've tried swapping card -same results.

I've tried using an external trigger and no trigger - behavior is the same.

I think we can rule out a hardware issue.

Could there be some sort of conflict with the software loaded on the RT system?

dug some more - seems the self calibration of the device mimics the capture issue - slot 2 works fine, slot 3 comes back with an error and slot 4 just goes out to lunch.

slot 3 gives the error -50403

"A transfer is already in progress. The operation could not be completed as specified"

I tried something else, I removed the interface card from the RTOS system and plugged it into the Windows PC

The problem goes away - so definitely something to do with the RTOS or RTOS tools......

I've reformatted the RTOS HD and reinstalled all the drivers with no change in behavior - could there be something on the Windows side that affects the RTOS operation?
