cRIO 9035 RT

[Xiao@Gemini]

Hello everyone, I'm running my RT project on cRIO 9035, my timed loop delay execution like two and half minutes after I click run. I couldn't figure out why. The second thing is that when the program running for 8 hours, the available physical memory drops to 10Mb, but it still running smoothly, I could not figure out where the memory leaks come from. I'll be very appreciated if anyone can give some suggestions. Thanks. Code attached.

Hey,

You said that it takes a while before your timed loop executes. In regards to that, I would check the priority of your timed loop to ensure that if you want it to run first that it has a higher priority.

is your consumer faster than your producer? did you set up a size for your queue?

No size for the queue.

The timed loop starts to read these signals two and half minutes later when I click run. That's not my major concern. My major concern is the memory leak, my front panel has lots of graphs, array indicators, and bar graph. Initially, 240Mb available memory, it drops to 10 after like 8 hours, I cannot find the memory leak, or the display from front panel did take such memory.

put a get queue status and indicator to check if the consumer can dequeue fast enough. if the number is growing, your producer loop is faster than your consumer loop. And not setting a limit on your queue means it will keep on queuing new elements, eventually you will run out of resources.
