Well, unless there is a leak, of course. :) The backup script uses exactly *one* pipe (between dump and ssh), and that one pipe seems to make all the difference between using barely 300 kB pipe kva, and hitting the 8 MB limit... > Is it really crashing? That's not supposed to happen. :( Yes, it crashes when it runs out of pipekva. I wasn't there when it happened, but I did get a frantic phone call asking what to do :| > [snip lots of useful details and suggestions] I'll see what I can do; with a little luck I'll have initial patches ready over the weekend.
