I am a new aand relatively naive Andressw and Unix user. I just lost a rather long message I was composing; this distressed me as you might imagine, and Bill Janssen said you would be interested. While the composiition window was open, I noticed that a previous message I thought I had kept a copy of was not aaround. I went to the Help document, and found out how to make that happen, and went into Set Options. Found lots of interesting options, and turned a number of switches, including bcc. Did no Alter's. Then not understanding how to get out of Set Options, I went back to the messages window and clicked on a mail folder name. Got the following message in the console window <warning:ms>Segmentation Violation signal caught; checkpointed server state... and the messages window disappeared. Started messages again. Then looked for a *.CKP file with contents like my composed message. Couldn't find one anywhere with the right contents.. Sniff. And I thought this couldn't happen. I'll try it again soon, after I make sure I have read my mail and mailed everything.

Hmmm.... I just did an experiment, and it looks to me like sendmessage checkpointing is totally broken. I know it worked once upon a time, but somewhere along the way some patch or something may have turned it off. As far as I can tell, message composition windows are no longer checkpointing at all. As the various options related to this checkpointing suggest, I put a lot of effort into making this work once upon a time. I have no idea when or why it broke, but I suggest that it should be added to the bug list, at the very least... -- Nathaniel

So much for experiments. Shortly after that experiment, my modem connection died while I was composing mail. I reconnected and, lo and behold, though my processes had all died, my mail-in-composition had been checkpointed. So it isn't as simple as being totally broken, but it doesn't seem to be checkpointing as often as it ought to. Maybe it's only checkpointing on something like a HUP signal, instead of the timer events it is supposed to use? At any rate, I don't think that the "Checkpointing messageserver state..." messages are also indicating a checkpoint of mail in progress, though they are supposed to...

my composition window has the nasty habit of displaying "Checkpointing messageserver state..." and never coming up for air. peter
