UNSOLVED MMM-Chart Module

[Fichtl]

Hello, I use the MMM-Chart module to display different weather data on magic mirror. Currently the magic mirror run into a out of memory after certain time.
If I deactivate the modules the memory consumption is quite less. The maximum nunber of entries for one chart is less then 900 single values.

I Installed the magic mirror from scratch and after I discovered the situation with a standard installation of Magic mirror on debian scretch I update the eletron to 5.0.0 but the result is still the same.

Everytime the chart jumpsup I restarted the magic mirror.

The magic mirror is rotated by 3 and I dont use the GL driver or the fake gl driver, because this dint work.
