[[Well, this one is strange. There was a lot of talk about it in the v6 issues, but it never really was resolved and it looks like it just went away (a Sun bug fix?). In any event, I included the most informative of the articles from v6n16 at the end of this article. -bdg]] I am relatively inexperienced in Sun systems so bear with me if this is a simple question. All I know is I'm having a lot of problems with it. We seem to be having some random network problem (runts, bad crc, etc.) and from time to time I will get "tbds out of sync" on the Sun console. This message is usually followed soon by "ie0 bark reset" at which point my system automatically re-boots. I'm certainly trying to get to the bottom of the network problems but I don't believe they should have such a dramatic effect on my system. First, could someone tell me what these messages mean? and second, is there any way to avoid this automatic re-boot? We're running some very long jobs over night and this 3am re-boot is giving me fits! Thanks for the help...

The hang appears to be the result of a bug in the driver. We saw a spate of these some time ago; they subsequently vanished as mysteriously as they had appeared (or did someone replace a board? I forget). I stared at the driver for several hours while these were occurring, and twice thought I had found the problem, but was wrong both times. It may be another hardware bug.
