Something calling viFindRscr for PXI0::MEMACC

[Mark_Ireton]

I'm looking into a communication problem with an LXI instrument and using NI I/O Trace (formerly known as NI-Spy).  I noticed that something is calling viFindRsrc for PXI0::MEMACC, opens a handle, and reads some attributes.  Then I see similar calls for several other resources such as PXI0::1::BACKPLANE, PXI0::2::BACKPLANE, then several PXI and TCPIP resources.

I'm concerned primarily about this unknown code interfering with my communications as well as the performance hit (about 300 ms per occurrence).  Does anyone know what is creating these calls and how to disable them? 

I've included a capture file.

Thanks, Mark

Hi Mark,

Could you please give more information on what calls you're making? It might help if you could upload your application. It looks to me like these calls might be lower-level calls that are part of the subVIs in your application. 

Could you clarify why you think this code is interfering with the communication? Are you currently running into any errors communicating with your device?

Thanks!
