Okay, I ran into the problem again. The reason for the delayed followup is that it takes a couple of weeks for it to manifest itself, and I was on holiday for a week at the end of May (hi Jordan, hi David!). 'ps axl' shows that all affected processes (pine, less, trn, irc, etc., etc.) are waiting on "ttybf2", if that rings a bell for anyone. I've upgraded our shell servers to 2.2-960501-SNAP and will continue to watch for similar behaviour. -- Brian Tao (BT300, taob@io.org, taob@ican.net) Systems and Network Administrator, Internet Canada Corp.
