Hog iPC bugging out badly

Hello,
I had a major issue with the iPC last night. I was running lights and the first two bands who came up I had no issues with. Right as Colby Caillat came on stage, the console started bugging out badly. My cue lists started disappearing, the palattes started showing randomly created new pallates, half the buttons stopped working properly, and the lights wouldn't respond to the console unless I punched it in manually (like, fixture 1 thru 8 @ full).

At that point, I ended up pulling the DMX line so the stage would at least remain lit as the console kept clearing itself out as well.

Does anyone have any idea as to what would cause this to happen?

Thanks,
Matt

    [QUOTE=jxgriffi]I'm curious as to what some of the implications would be.

    I've seen many cases where "flakey" behavior was traced to KVMs. Intermittant behavior during BIOS POST, random reboots, etc.

    The KVM has to pretend to be two keyboards to the computers, and control the real keyboard itself. That means it has to track the state of all three sides, including keyboard mode, scancode set, held down keys, etc. If it gets confused, or misses one byte of data, there's no good way to recover.

    Given how KVMs are installed, it's easy for them to get static zapped, have ground loop problems, etc.

    KVMs are great, very handy, but you do have to watch out for problems. Personally, I would not use one in a live-show environment. I know many people who do though.
