Yes, you are right, Simon,
I found it in app.cfg as:

sqlalchemy.max_overflow=40 # Bumped up from 10
sqlalchemy.pool_size=10    # default


thanks a lot.

I think turbogears is loading your sqlalchemy parameters from a config
file (dev.cfg perhaps?). You should look for a line of the form
"sqlalchemy.max_overflow = X" and delete it.

Hope that helps,

Simon

Thanks for the tip, Michael, I'm going to see how to manage with this
keyword (because I'm not specify such parameter, but probable is turbogears
who uses it by default).

you can't use "max_overflow" with the default connection pool used by the
SQLite engine, remove that keyword.
