I am trying to use ZODB 3.10.2 on my web server which is running Debian and Python 2.7.1. It seems like every time I try to access the same database from 2 different process
You can not access the same database files from two processes at the same time (which is obvious). That's why you get this error. If you need to perform actions on the same data.fs file from two or more processes: use ZEO.
