I made this large live edge cutting board about 5 years ago. It has been perfectly fine and stable for a while. All of a sudden last night, it popped and the entire board is twisted.
I had some white oak flooring in the shop and I decided to use it to make a top for a workbench. I glued all the joints together as I assembled the top - something that I would never do with a hardwood floor. On several occasions, the floor has split, not at the joints, but in the hardwood itself. Not a single glue joint has ever opened up. Every time that the top is refinished, I end up filling the cracks with wood filler. I have another workbench top that used the same hardwood flooring, installed without glue. It has not cracked in 20 years.On the plus side, it proves (yet again) that the glue is stronger than wood.
Given how thick the board is and since your wife wants a lighter cutting board anyways, in your shoes I'd repair the crack and surface out the warp.

OK, but I think it would be hard for Cyclop. to keep all those little wood squares together without glue.I had some white oak flooring in the shop and I decided to use it to make a top for a workbench.

I did that with a commercial made cutting board I’ve had so long I don’t know where it came from. Probably my grandmother’s kitchen. At some point one of the boards decided to warp and popped the glue joints. I ran it through the table saw along the bad joints, scrapped the warped piece and reglued it. In the process I planed it smooth. now I have a slightly smaller, slightly thinner cutting board and really like it.On the plus side, it proves (yet again) that the glue is stronger than wood.

Your dishwasher probably drains to the garbage disposal which puts the heated water in the sink drain where it vents up under your board. just another possibilityMarks suggestion may be the issue. The board sits into the sink where the bottom is exposed to water. We had family over for lunch and it sat on the counter all day.
And i coated it with beeswax/ mineral oil as I remembered, no regular schedule. I had ran out and needed more beeswax
