Hi,
we are using Hibernate v3.2.6 & DB2 v9.1.6 in our application
our code throws below error which is not consistent to any particular DAO method,
I mean to say same method would go fine some time and some time might throw exception

did any one experienced this issue before ?
Appreciate your time.
