You should report this to the ZODB mailing list "mailto:zod...@zo...".

There have been various (about 3) reports about "POSKeyError"s
in connection with Plone. They, too, may have data loss as
a cause.

Zope 2.6.1's "pack" was known to have bugs that could lose data.
Nothing like this is known so far for Zope 2.6.2...
But, maybe, you can now reproduce such a thing?

No. This should not lead to data loss (other than the old versions).
