Calling niDCPower Wait for Event on multiple channels simultaneously will rarely return error -1074116981 on the PXIe-4162 and PXIe-4163

When niDCPower Wait for Event is called using the Measure Complete Event on multiple channels on a PXIe-4162 or PXIe-4163 in parallel, a channel will occasionally return an internal hardware error, -1074116981.

Once in this state, the error can only be cleared by performing a device reset.

The error message looks similar to the following:
Error -1074116981 occurred at niDCPower Wait For Event.vi

Possible reason(s):
Internal Hardware Error. Contact NI support.
Additional Error Info: Applicable Iso Captured: [RegPortDcBusTxOverflow]


Workaround:

Use a simple for loop instead of parallel for loop around the niDCPower Wait for Event (using Measure Complete Event) function call.
