I am running ScreenConnect on some Rasp Pis and the Pi eventually hangs up and then it will crash and require a reboot to allow ScreenConnect to work again.

This is in the ScreenConnect logs:

#

Is this more an issue with Java or an issue with the actual client?

Would limiting the amount of MEM Java can use fix this? I tried using export to push limiting options but export does not work on Pi.

Have you deleted any JDK files recently? This question suggests you may be missing some files from your java installation. Just in case you could try reinstalling java.

  • I can try that but I've not deleted anything. I did an apt-get install oracle-java8* and left it like that – Jason Nov 25 '15 at 4:13
