I've seen an industrial switch running Node. Whenever it was collecting stats, the switching fabric was locking up.
- seabird 8y agoCan we hear a little more about this? It seems so far off the deep end that I'm morbidly curious about the reasoning behind it.
- varjag 8y agoIt was a managed industrial switch from a 2nd tier manufacturer that am not going to name. Was found out because it was breaking the fiber ring on site. My colleague opened it, hooked to a UART, accessed the system and found it's running a Node application for Web UI. On (self-refreshing) status page it was accessing exposed to userspace PHY registers to read out the stats and not in a clever way, blocking up the switch.
