Webos restart or crash end layout

Hi,
i’m using Xibo 2.03
webos version 3.2
ipk version 2 or 1.8

sometimes at the end of a playlist i get this messages from LG webos
“This app will now restart to free up memory”

if all goes well Xibo restarts if not it goes to HDMI1.

anybody encountered this problem ?

any ideas are welcome.
