Martijn, you're right. Nobody would use Win98 on production systems. But quite a few people use it on their notebooks or home PCs for development, I guess. At least that is what I do. If your assumption that a Windows cache problem is the reason for the data loss, is right, that would mean that Win98 must be holding the whole DATA.FS in memory/virtual memory without saving for hours! In that case it might be a good idea to warn everybody to shutdown and restart Zope under Windows 9x after major changes. BTW: So far, I've never lost data when I just "killed" the Zope process. So Windows seems to save data at least in that case ... Joachim. [RH]Hm, I have been developing for quite some time on an feeblish win95 machine at home, which repeatedly crashed, but I have never ever lost committed transactions. Strange.

This sounds like Win98 is using a write-cache that didn't get flushed to disk because of the crah. IIRC, Zope forces write cache flushes, but it could well be that Win98, being a client-patform, ignores that for performance reasons.

Then again, who'd use Win98 for production sites?

[RH]Ok, that's true
