In the past few days, I've had seven wu's error out. Oddly, four of them with exactly the same run time.

Won't let me edit.

I said seven, total has increased to nine now.

Edit is within 60 minutes only, your posts are 1 hour and 15 minutes apart, 75 minutes.

Yes, I know, I hadn't thought it had been that long.

Error count up to 12 now.

14 errors now. Some quick, others after considerable run time. Have not set no new tasks but will if this continues.

Three more errors today, (in the last 12 hours), no new tasks set. I think the failures are happening when the system is restarted, an inconvenient, but necessary action for me right now.

In your lot for one of your error units it says this:
"Skipping: /nbody_graphics_point_point_size"

LOTS of people have trouble with the n-body units, I think some are reporting a 5% error rate, you can set it so you don't run them anymore and see if that helps.
