First, I'm impressed you are able to make 4 Titans work in this environment.
Is there some reason you are only using 3 of them for GPU processing? Since all the cards match, you should be able to use the GUI card for processing as well.
I only see the GPU mem error in one log, from today, using the ARTE project. It appears that GPU 3 is not happy about something and is not responding properly to CUDA commands.
Since it seems to be only 1 specific card having the issue, there might be an issue with the card itself. Looks like the error may have happened during or just after some rendering, so perhaps an overheating issue?
As a test, go into Resolve Preferences, System - Hardware Configuration, set the GPU processing mode to CUDA, set the GPU selection mode to Manual, and uncheck the 3rd Titan card. Save the prefs and restart Resolve. See if that makes the issue go away.
If not, please provide a new log after the issue repeats.
