I have BI setup to record hourly segments. Over the last few days I've been getting what appears to be hourly email notices from BI that there is a possible heap corruption. What does this mean? I couldn't find any reference to this in the help files. Below is the latest email I've received:

I can't recall what version I was on at the time of my first post, but it would have been the latest version at that time. I'm currently on the 'now' latest version (5.5.0.13). Anyway, I no longer get the 'possible heap corruption' warning or error messages. I still don't know what 'possible heap corruption' means.
 
I noticed this error as well on a couple of different v5 builds. Currently running 5.5.4.5 as that is when my support plan ended but I had it on older builds as well. A reboot fixes things for a couple of weeks maybe. I also have been getting recurring crashes on v5 but the windows service is set to restart forever so I don't really notice in practice.

Running Deepstack on CPU if that matters. One thing I noticed was that the Intel driver for the GPU has updated itself to 27.20.100.9664 ... I was pretty sure I had disabled updates, sticking to a known good version. If that is still a thing?
 
Just got this "Possible heap corruption" error today on v5.5.9.6. Don't think I've ever seen it before. Guess I'll see if it happens again.
 
Getting a ton of these now. As last count 21,454 errors over 2 days. Seems to have started when I updated to 5.6.4.2.
