This is what caused me to abandon HHVM for plain ol' PHP around a year ago. I was running it in Docker containers and the memory leaks would regularly crash my containers if left unattended for more than a couple of days.
It was quite frustrating because I noticed some definite performance gains (e.g., ~2x faster page loads, etc.), but ultimately opted for PHP's stability.
The benefit to running all this in Docker is that I can swap HHVM back in relatively easily (unless it's changed really dramatically over the past 10 months or so). Your comment has me tempted to give it another shot!
