code.XXXXXX (number) files in Config directory

Configuration
1

After 0.87.1 update, in my Config directory about every 30 minutes I get a new file named code.XXXXXX (XXXXXX is a not sequential number) with dimension of about 160 MB.
I’ve not changed anything in my configuration nor added sensors/switches/lights…
Where are these files come from? How to stop their creation?

PS: HA is running in Hass.io installation on a Raspberry PI3 B+

Find the trouble… it was an addon (LMS Controls) that crashes HA 0.87.1 due to some incompatibility I’ll try to discover. But all was perfectly working until 0.86.x
