<p>In my mechanism driver, I am reading/writing into sql db
in a fixed interval looping call. Sometimes I get the following error when I
stop and start neutron server</p>
<p>InvalidRequestError: This session is in 'prepared' state;
no further SQL can be emitted within this transaction.</p>

<p>I am using context.session.query() for add, delete,
update and get. Please help me if any one resolved an issue like this.</p>
