I need to add a script to do something after the print is complete but it looks like all the external calls I am making now result in this error message. I know this use to work and the pi was rebooted recently. Running build 1556. I even tried something simple like: [[Exec echo 5 > /home/pi/test.txt]]

Please, check your system memory usage data. It could not get memory from OS to run external command/program.

I knew I should have posted that at the time. I had plenty of memory when I did TOP from the command line. Almost no swap used and seems line plenty of free ram left to be allocated. I will test again and get the numbers.
