We are currently using two Sequoia 2.10.6 controllers on two separate
servers running CentOS 4.5 and connecting to PostgreSQL 8.2.4 at the
backend. We have a single instance of Tomcat 5.5 connectiong to the
Sequoia driver.
We are currently testing an application with Sequoia to hopefully go
into a live environment but we have received this error:

Can anyone tell me what it is, and in what circumstances it will arise?
Thanks
John
