don't know what's going wrong. pls me rid of warning causing other problems.

from research related stale connection or not closing connections correctly. have found related ticket here. please review , let me know if helps. if not can provide more information of environment. tomcat fullversion? looks using hibernate. version? there other errors maybe in application logging related?
