I was greeted with a crash today but I do not have any experience interpreting the dump. Hopefully I have provided the relevant information.

@LarryFahnoe That's likely https://redmine.pfsense.org/issues/15684

Which is fixed on 24.11.

@kprovost Though my eye is untrained, I would agree that mine looks very similar. It has happened only once, so I will keep an eye on it and watch for when 24.11 goes GA. Thanks.
