but I am not sure what could have triggered this. It happened only once. Will it be possible to know the cause?

I would update to the latest patch version which is 2.9.14. I would imagine its fixed but you can search for it in the changes.

v2.9.6...v2.9.14

Hi Derek,
Thanks for the quick response.
I had a look at the code and there seems to be changes where I had encountered panic.
Just wanted to know if 2.9.14 is stable version and can be used in for production?

Thanks
