Well, let's see...

You've basically told BDB:

"Hello, you have a safe place to store all your data files for suffix X in 
directory Y."

You've then told 2 (or more) *different* instances of BDB databases they 
can use the same directory Y.

Since each instance creates environment files with the same names, you've 
created a MAD (mutually assured destruction) situation, as they'll 
overwrite what the other is doing.

You *must* specify different directories for each database instance to 
store their files in.

The same thing would happen with any database type system where you told 
different instances of databases they could use the exact same resources 
for storing their data.
