Best is - and after talking back to the operation's guys, to try to reproduce
the error already with an 1.1 installation (Silva-1.1.5 and ExtFile-1.4.2). As a
first point it would be important to see wether at all you can reproduce the
errors on the Silva-1.1.5 level with ZEO and Samba.
Samba for ZEO: All tests here were done with assets on a Samba share. The single
instance tests (Non-ZEO) where we do not observe the errors were without Samba.
No test were done with ZEO and NFS e.g.
I also upload the Config.py of the ExtFile product.
