Guys, anybody please help me to get rid of this internal error. We have done a myrio project on image processing application. Its very urgent..plz.....

Sorry, I don't have the advanced signal processing toolkit installed. I am curious why you are constantly switching between integer and floating point. Wouldn't it be more reasonable to stick to a single representation?

Are you trying to run this on the myrio? How big are the 2D arrays?

Hello, I ran into same problem, got any solution?

No obvious memory leak, memory usage around 40 %, BUT I get 50 % CPU usage of the main process (one core to 100 %, other one to almost 0 %) at the moment when the application stops working. It keeps that way for 10 minutes until the watchdog restarts the system. In MAX, Error log shows this error:

My problem was a software bug obviously. First, cRIO worked for 1-3 hours and then threw error 2 in LabVIEW Log in NI MAX.

The problematic VI is a for loop with parallelism, inside of it was while loop which ran "permanently". In this loop there was a disable structure, and INSIDE THE ENABLED CASE there was one VI (with shared reentrancy). 

I focused on the disable structure because its behaviour was suspicious when ran through LabVIEW Project. Parallel for loops are not debuggable by its nature, so when you turn Highlighting Execution on, you cannot see anything happenning in parallel for loop. But, I could see the dataflow in wires and the green arrow on the subVI inside the disable structure, which caught my attention as it should not be possible. I could even place a probe on the wires inside, it should show No Debug Info when inside parallel loop but instead it showed Not Executed. There is some weird interaction between parallel loop and disable structure.

Just removing the structure and leaving the code the same as before did it for me.
