This didn't use to be an issue but i find as i get into more intense simulations and more interconnected sims like Whitewater, my sim and bgeo files just stop working.

It feels as though a Houdini scene gets corrupt over time as it starts quite stable, but once the slightest issue happens no matter what i try to do it starts happening more frequently. The problem gets worse over time. I work on 2 different machines with Houdini and I've experienced the issue on both.

Does anyone have any insight on this? It's been a major problem for me for the past couple weeks…

Sounds like your hard disk is going bad.
Is it an SSD or an old platter stlye hard drive?

I've tried both the SSD on this computer and the larger terabyte hard drive, both have the same issue. It's not gating though. The water sims i'm able to cache. It's just frustrating having to bake out far into a sim to get a good bit of froth going so you can adjust your materials and renders only to have to restart it all over again once you find your look.
