One of my colleagues (Doug Ambrisko) has a desktop machine which has been exhibiting the symptom as recently as 1.43, thankss to the combination of things he does with the (abused?) machine and the load I put on it in the wee small hours of the morning using amanda (driving dump) to back it up. We were closed for the week between Christmas & New Year's (i.e., the first 8 days of Christmas), and he didn't get back to the office 'til the following Tuesday. I ran backups that week anyhow, but that wasn't enough to trigger the symptoms. The latest recurrence of the problem was yesterday (using the 1.43 rev. of the code); he said he would be applying DES' patches; I *thought* he meant that afternoon. Based on the results from this morning's backups, it looks as if he may have neglected to re-start inetd; I'll chat with him once he gets in. (Foggy here this AM, so he may be delayed getting in.) Historically, the failures have taken from 3-7 days to recur under the load mentioned above. david -- David Wolfskill UNIX System Administrator dhw@whistle.com voice: (650) 577-7158 pager: (650) 371-4621 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
