Controller Crash on Warm Download

Dear Stephan,

I was hoping if you could provide some urgent support. I am on site before startup phase and everything was seeming to be wokring fine in our system. However, I made a warm download after making some minor changes in my application and controller along with its redundant controller went in fault. It is worth noting that it downloaded perfectly when I downloded in an empty controller, but the issue only forward on a warm download. Most of the testing was done on a simulator where no such issue was ever seen. I am using 800xA, 5.1 FP4 and this is the HI controller PM865 with SM811. I have attaced the controller logs (2 warm downloads in quick succession) for your reference. I would be highly grateful if anyone else has anything to add on this?

Regards,

Haidar
