Apex heap size too large

I have a dashboard that I built in SKUID, which was working wonderfully. I recently received an “Apex heap size too large” error, and updated to the latest Rockaway release which seemed to fix the heap size issue. It has just recently come back and I’m not sure what is causing this. The page has many models and rows, but not nearly as many as I’ve done in the past. I’m not sure why this is happening, any advice would be appreciated, thanks!

This has happened to me before. I reduced the max number of rows allowed by my models upon page load and decreased the number of fields displayed in the tables… This fixed the problem permanently.
