Strange error with cRIO and Scan Mode

[Jed_Davidow]

I am scanning two cRIO modules on a 9012 controller + 9112 8-channel backplane in scan mode, and I am calling the "Scanned Variable Read" function.

I am seeing this error, every few scans:

Error -2132869099 occurred at Property Node (arg 1) in PolymorphicModuleScan.vi:7->sampleData2.vi->ZDAQ_cRIO_Target_Main.vi

Possible reason(s):

LabVIEW:  (Hex 0x80DF0015) A deployment transaction is in progress.

Searching for this error on NI.com gives no help at all.  This is the first time I am seeing this (I have been running this code for a while without error).  All software is from the August 2011 dev set.

Solved:  I was calling the "Get Scan Period.VI" scan mode function at 1Hz.  This seems to have caused the 9205 (not the 9237) to produce that error.

I removed the call to the offending function and this solved the problem,
