We have an area of our product that can, depending on certain conditions,
produce lots of rapid transactions all at once. We’re getting many reports of
POSKeyErrors at sites where the transaction volume is higher than others. They
appear to coincide (in many cases, at least) with zodbpack runs.
You should be able to arrange to some time in the past. You may need a
custom pack script. (I don't remember off hand if zeopack accepts fractional
days.) But maybe packing some small time period back (say 1 hour)
would work around the issue.
