RAM drive keeps disapearing once in a while

Hi,

I use the Lucee RAM drive to store images and to make thumbnails very
quickly. Once in a while (I don’y know exactly when), the RAM drive is gone
and can not be used (this was also the case when I used Railo). I don’t
know why. Is there anybody who can help?
