I believe there is a recent regression in the math caching system. It appears that newly added equations aren't being cached properly. The images get generated on save, but it appears that Mediawiki is forgetting that it has already made them and is attempting to regenerate them on every save / preview.
This does not seem to be the case with old equations, where the caching continues to work, but only with the caching of recently added equations.

Possibly related: the Math reference desk was rendering impossibly slowly (to the point of timeouts and WMF error pages) a few days ago. Discussion at:
