I am getting this temporary error on my errpt:

Never had that one but did you read the failure cause and the recommended actions? Did you investigate the system in that direction?

Also searching this forum with it's search function can help, as well as googling for it.

Years ago we used to see this problem with serial attached CRTs,
when they had cable/connector issues. It indicated the tty was
"flooding" the system.

Here are a couple of old posts about the problem:

I cause these errors on our AIX 6.1 box today. When I accidentally cat enormously large files, these errors show up. I think the error basically means some one is writing a lot of text to their screen.
