Crash after a few seconds of operation

[Flavourdynamics]

Steps to reproduce:
16xIO
create 4x4 panel, parallel driver
effects tested: fire, praxis, radar
let run for 40-300 seconds

Expected behavior:
continuous operation

Actual behavior:
crash after a 40-300 seconds"
resets after crash
no LED output on recovery
loops per second is much higher (suggests nothing is being driven)
restart runs the effect until another crash
