The first error message is the clue. It says "sd0(ahc0:0:0): MEDIUM ERROR". This means that the disk sd0 is experiencing unrecoverable read errors, either due to a developed bad block or a failing disk. Since that is most likely to be the system disk, you'll see all manner of other strange errors that result from the read error.

Hope you've got a good and recent backup. You need to replace the disk and you won't be able to trust it's contents to copy them to the replacement disk.

All of the other error's (the inetd error, socket error, and swap error) are caused by the disk error. The disk is experiencing read errors. This causes lots of things to fault as they or something they are trying to do attempts to read data off the disk.

You need to find out if it's a bad disk (highest probablility) or some other problem (flaky scsi controller, bad cable, bad termination, or another devce on that scsi bus that's malfunctioning).

bsher, I answered your other question regarding these error messages 2 weeks ago, and jlevie has just confirmed everything I said. It appears you have ignored a potential system failure all this time, while continuing to ask questions for ridiculously few points.

From your record I see you have asked 19 questions and graded very few of them. I suggest you a) start acting on the suggestions of experts and b) start treating us with the courtesy YOU appear to expect, by allocating a reasonable number of points (i.e. EEs suggested levels!) to questions and grading them when you have an answer.

jlevie, I suggest you lock this question so bsher can't delete it, and at least you'll get an autograde - eventually!
