ADE7878A & ADE7816 common issues - AFE's resetting

Hello gents I hope all is great.

I have a customer that is developing 2 projects using ADE7878A and ADE7816. He has been successful by now with metrology and measurements but there is one issue (common to the two platforms )  that is calling my attention:

- Both AFE's are resetting itself occasionally. It really sets RSTDONE from Status 1 and the IC needs to be reloaded. -  I do not have a clue o what could be causing this issue.. can you please give me one hint of where to search for?

It is I2C commns using bitbang configuration.
