I'm not sure if this is a known bug, or if I've stumbled on something new. I've packed a 300 Mb Data.fs recently (leaving 7 days of history). Thie resulting data.fs was still biggish, so I packed it again (leaving 0 days of history). Then interesting effects started to happen: a Folder just disappeared, then appeared back for a short time, and then disappeared again after a couple of seconds. (Of course, this might have been caused by caching effects or a bug in Mozilla.)
That's what happened to me for 2 times... Objects simply disappeared after packing (they are appeared for a short time too in one case, before they definitivly disappeared). Do you use ZEO?
Is this a known issue? I do not think there were any Undo records involved, and I'd expect fstest.py to barf if there were any dangling backpointers, so I suspect collector issue 875 does not apply here. (I use fstest.py from Zope-2.6.1-src, not a CVS version.)
Please add it to Collector 875. The ZODB-Gurus should decide if it's related or not. And I'll hope they'll hurry up...:) Cheers, Maik
