close: illegal multi-threaded access detected

[anuradha devi <da...@yahoo.com>]

Hi,
We are working on a web application which is built on
OJB0.9.5. Particularly we are using ODMG for
transaction maintainance and PB API for database
operations.
When we are performing load test on our application we
are getting this error.
Has anyone faced this problem earlier or anyone has
any idea about this?

Please let me know what can be the probable cause of
this,
