I had a curious case of missing-but-present blobs in an old Plone service, configured with a Zeo server and 2 Zope instances.
The root of the problem (I think) was that the blob folder configuration was broken: the Zope client instances were configured with shared blobs to “off”, but they were really sharing the same caching folder.
In the end, the blobs were loaded by the Zope services and everything appeared to be working, but when I’ve tried to move the blobstorage folder to a new machine, I ended up with missing blobs.
