Debugging PosKey Errors in ZODB

I ran into a KeyError while packing a ZODB database in production. It lead me to a PosKey error while loading objects which did not exist anymore. For those of you in a similar situation here is what I found very helpful:

• Using zc.zodbdgc (fix PosKeyError’s)
• Fixing Broken ZODB Object references

Packages I’ve found useful:

• ZODB3 and it’s provided scripts (fsrefs, fsoids)
• zc.zodbdgc
• eye – a ZODB browser

Happy debugging!
