I have had the same problem for some time, and also the same temporary solution. I thought it had something to with cache, memory, logs etc. But i think I solved it by turning on PowerD. All settings are set to HiAdaptive. It was turned off by default.
It has been running for 2 weeks now without any issues, no reboots. Something which wasn't possible before. I hope this helps.
