This is what I've got from digging lostash. Three types of error happen: 1- Saving a page fails because Lua engine returns false one example, you find tons of it 2- It gets propagated to ChangeProp an example 3- And refresh links job an example. I think the first type of error is the source of the other two.
I put the whole backtrace of the first type for debugging:
