NI cRIO 9049 reboots when running RT application as a startup rtexe

[AshwiniWini]

Hi all,

I am using cRIO 9049 for my application. I am facing cRIO reboot issue when i am running application as a startup app. Same software works perfectly fine when i run that through RT Launcher.

I checked CPU usage when running though LabVIEW development software, its ~45-50%, also there is enough memory on cRIO.

I am using LV2021

Any thoughts, why this could be happening?

Thanks and Regards,

Just to clarify, you need to reboot the RT target when you deploy and set a startup RTEXE from LabVIEW ADE for the startup setting to take place.

Are you saying that your cRIO keeps rebooting? How long it will run before rebooting? 10 mins?

Thank you ZYOng for response.

cRIO reboots once I deploy my .rtxe as it supposed to be. but after that within one-minute cRIO reboots and keep on rebooting.

It sounds like the cRIO crashed due to the memory leak. Try to log and monitor the memory usage. See Error -2147220623: Largest Memory Block Property Does Not Exist

Thank you ZYOng.

I monitored memory while its running through development system, it's quite low. Also monitored memory when its running as a rtexe, I didn't see any surge in memory.

Article link given by you, recommended trying disabling 'Embedded UI option', when i disabled it, cRIO is not rebooting.

But for debugging purpose, i need to see what's happening in my VIs, is there any other way than disabling 'Embedded Ui' option?

Also, I still don't understand what's wrong with my cRIO.

Try checking Error Log File for My Real-Time Controller Crashes

Thanks, ZYOng.

I am getting error when I try to open error log using NI MAX, but I managed to fetch LV Error file from /var/local/natinst/log folder. Please see attached screenshot, it says 'address not mapped to object'. I found similar issue's post on forum: https://forums.ni.com/t5/LabVIEW/cRIO-9068-segmentation-fault/td-p/4063417 but it is unresolved.

Does anyone know about this Error?

After digging more log files, I found Kernel error file (Please find Attached). Can you please tell me, what could be the reason for reboot?

Thanks, and regards,
