Don't know what this error means

#1

From time to time, in an undetected fashion, or due to no apparent reason I get the following error:

IllegalStateException: Already value [ContainerResourceHolder@2326a44f{storeName=‘MAIN’}] for key [com.haulmont.cuba.core.sys.persistence.PersistenceImplSupport$ContainerResourceHolder] bound to thread [http-nio-8080-exec-14]

Can anybody shed some light please?

Thanks,

Carlos Conti.

Hi Carlos,
Do you have a stack trace in the log? If so, please provide it.
