i run pd on raspberry pi, with some sensors connected, and control from an app via OSC

there are many things that can go wrong, pd actually just does audio playback of 4channel files.

this thing is running as an installation in a museum, so far quite stable, since the last week there was one ocasion where the raspberry or pd crash.

i actually have no idea how to find out what why this happens

(have to find out where to find crash - reports…)

maybe it would be a good thing to automatically shutdown the raspi at 18h everyday.

thanks for the tips!

Please excuse the obvious answer, but it would be best to first find out
why Pd would hang and solve the problem at its source. Other
hacks/workaround cound include:
-Depending on what your installation is about it could be possible to
restart Pd or your computer every day. A simple timerswitch would
suffice.
-Have Pd send a (heartbeat) message to another program via FUDI or OSC.
When this message is not received it could indicate that Pd hangs and
that other program could kill PID1 and restart.

By the way: Is there a reason you run Pd as root?
