Never had an issue with a CIB (except being unplugged from USB!) - The RDM compatible firmware on Artnet boxes has been known in few cases to cause DMX fluctuations, and therefore might explain the random white flashes - but not on the other 'cib' server... You should be able to downgrade the firmware to a non RDM version using 'DMX workshop' on a PC - check with Simon or Wayne at AL if you have any issues.

You should also be able to monitor this using the HUD in catalyst as discussed - either with a separate Mac over Ethernet - or on either of the servers (the one with the artnet box preferably...) any changes in DMX will be highlighted on cyan and seen if they are 'flickering' - alternatively - use an AL microscope (think you can do a flicker finder test on it??)

Try terminating the CIB DMX output if possible - most CIBs are auto-term, but I have had to terminate the DMX in the past.

Two other thought:

- Are either servers connected to your inter/intranet? It would be worth disabling any file sharing or VNC if its is enabled.

- Are you syncing playback across servers using sync id at any point when flashes occur?


However, it does seem like a heat issue - especially due to the random nature of it.

Re content freezing issue on the specific cue - still can't solve that one - will have a look at the system and content with the hog show when it returns next week. (don't delete the content!)
