8x JS scripts crashing iRidium Server on Raspberry Pi

I have an iRidium Server project which connects to 4x Global Cache IP2SL connected to Extron SMP111 video recording devices. I have two scripts - one to query the recording timecode every second and the other to query the recording state (initialising, recording, pause, stopping). In total there are 8x scripts querying every 1000ms. This works well but after a few minutes the server locks up and restarts. I am guessing it's due to 8 simultaneously commands happening, or perhaps because i'm getting two feedbacks from one driver simultaneously. 

One thought to solve this is to stagger the reqesust i.e. have one requesting every 500ms, the other at 501ms so that the there is only one response coming in at a time from one driver (or potentially staggering all so that there is only one feedback at any one time). 

Is there more a clever way of doing this?
