Exception when reloading my EAR / linked with pool of session bean ?

Hello there,

 

When I redeploy my EAR on Jonas (5.2 version) I noticed this exception
(not every time) : 

 

AbsTransactionInterceptor.handleContextContainerTransaction : Exception
(not application exception) in business method

javax.ejb.EJBException: java.lang.IllegalArgumentException: Cannot get
element in the pool at
org.ow2.easybeans.proxy.client.AbsInvocationHandler.handleThrowable(AbsI
nvocationHandler.java:176)

 

It seems to be linked with the loading of a Timer session Bean and the
associated pool :

Please can you help me ? Is there a setting in Jonas to change to
increase session bean pool ?

 

Thanks a lot.
