ORA--03127 with JDBC OCI driver

first our environment: Oracle 8.0.4 on Solaris 2.5.1, JDBC OCI driver 8.0.4.0.5 on NT 4.0.

The application, which raises the error 3127 is a self written server, which handels multiple self written clients. Each client connects to its own thread of our server, which itself has a connection to the database via JDBC. The server starts a transaction, does some selects and closes the transaction. If two clients try to get some data from the server the above message occurs. 'cause I'm not the big java guru, so I have no idea where to start my investigation. Is ist possible, the the error occurs, when two threads use the same connection?
