Maybe this is the cause, I’m not sure. I still think it should terminate gracefully and give you a user friendly error and continue with life; not crash your application. But yeah, without that data you mentioned it’s hard to troubleshoot/reproduce.
But I will backup again in the not so distant future and if it crashes then (after more memory etc has been accumulated) I will give you some material to work with.
Until then I will see if the scaling up of the pods helps.
I’ll keep you updated - better leave this thread open for a little while longer if possible.
