Since the file is decompressed without warnings I assume that the scp went fine. Anyhow, when I had decompressed the file I got corruption in the middle of the patch. The corruption affected only a couple of lines, 10 or so. The problems I experience are not repeatable. Everything went smooth after a reboot. I usually reboot the machine when it's messing with me, that helps.

They're rare for me as well, but I've had a couple in just a few days now. Maybe the file corruption became heavier since 2.3.6? > I understand that very well. Btw, I started to store important stuff on NFS. I can't stand NFS. Files, or entire directories vanish from ls, but I may still open them if I specify their names directly. I think I've been talking to you about this before. - Ulf
