[SQLObject] <class 'sqlobject.dberrors.ProgrammingError'>: Commands out of sync; you can't run this

Hi

Every few weeks, my web server, which uses sqlobjects, gets stuck with this
error:
<class 'sqlobject.dberrors.ProgrammingError'>: Commands out of sync; you
can't run this command now

It sometime recovers after a few hundred transactions, sometime, it doesn't
and remains stuck in this state.

It seems that all connections in the pool are "bad".

Do you know a way of reseting these connections? conn.commit()?
conn.ping()? kill the connection (how)?

After looking at the code, I'm thinking about the following patch:
in dbconnection.py, in _runWithConnection, I would like to catch this
error. If it happens, I would reset the connection, then retry.

Or should I do this in mysqlconnection.py, in _executeRetry?

Is there a way to know what was the previous transaction that causes this
problem on the connection?

Thanks for your help.
