DefaultListableBeanFactory Error in Spring MVC on Jetty

[paddydub]

Hi,
I'm having a problem with a neo4j - Spring MVC webapp i'm running on Jetty . I have tried with both Jetty 6 and 7. It will stay running for approx 1 hour and then I have to restart Jetty. It is running on a debian ec2.

I get the following error from Spring MVC in the jetty stdout log file.
I'm not sure what is going wrong , or how to debug this any help would be appreciated

Thanks
Paddy
