Where is this pack issue documented/discussed?
Also, does RelStorage have a bug tracker anywhere?
I have a main ZODB storage in a normal RelStorage with several
BTreeFolder2's mounted into it that come from a history free storage.
I'm using Zope 2.12.7 with ZODB 3.9.6
I attempted to pack the history-free storage with the following config:
<relstorage destination>
pack-gc true
<mysql>
...
</mysql>
keep-history false
</relstorage>
The pack was going on while a batch process was pouring data into the
ZODB by way for a loop with one transaction per iteration.
The pack succeeded fine with no errors but about 10 minutes after the
pack started, the batch process started throwing POSKeyErrors of the
following sort:
File
"/var/buildout-eggs/ZODB3-3.9.6-py2.6-linux-i686.egg/ZODB/Connection.py", line
897, in _setstate
p, serial = self._storage.load(obj._p_oid, '')
File
"/var/buildout-eggs/RelStorage-1.4.0-py2.6.egg/relstorage/storage.py",
line 462, in load
raise POSKeyError(oid)
POSKeyError: 0xf30dbd

It looks like these errors are occurring through the web client to this
ZODB as well now.
Any ideas what's going on here? What more useful information can I provide?
cheers,
Chris
