>             Project: Geronimo
>          Issue Type: Bug
>      Security Level: public(Regular issues) 
>          Components: connector
>    Affects Versions: 1.2, 2.0-M7
>         Environment: Geronimo 1.2 from geronimo/sever/branches/1.2 (01/04/2007)
> RHEL 4
> SUN 1.5.0_10 JDK
>            Reporter: Christopher James Blythe
>            Priority: Blocker
>
> Looks like are some concurrency issues with Connection Tracking in Geronimo 1.2.
> - Built Geronimo from geronimo/sever/branches/1.2 (01/04/2007)
> - Deployed Daytrader (built from geronimo/daytrader/branches/1.2)
> - Stressed "EJB" and "Session to JDBC" mode with multiple clients using load driver
> Both tests resulted in the following exception when more than 1 client was driven.
> NOTE: I went back and double checked on Geronimo 1.1.1 and this does not occur.
