I sort of expected that.

It's possible. It's pointless. It won't help this issue in all likehood.
But if you feel that's best then go in peace with your decision.

And about my problem, it was the way that i used the BrokerProxy class, because this was causing the memory leak!!
Have a great life!! |

Again, without seeing any actual code, it's really impossible to diagnose anything. The clearMessage() method is only useful for freeing up memory associated with MbMessage objects, but the JCN could be creating other types of objects ...

It's not at all obvious why a JCN meant to "retrieve email with javamail API" would be using the BrokerProxy class, but as long as the problem is resolved ...

Can you please be more specific in how your issue got resolved.
I am sure that there are more people out there using the broker proxy or planning to use it that would love to know.... Thanks

Oh it's so simple, when you get the localinstance of broker proxy, you have to do'it only one time, and i was getting each time i execute the evaluate function. it was causing the leak memory.

Hi rekarm01!
sorry because i don't post my code, but i was busy searching for information about JVM-WMB.
I was using the BrokerProxy class for retrieving "UserDefined" properties. |

I hope you opened a PMR with IBM. This memory leak should not happen especially if you disconnect every time you are done with using it...
Just as an additional information what did you do? Create the brokerproxy as an initialized field?

Typically, the JavaCompute node uses its own getUserDefinedAttribute() method for that ... not the Message Broker Java API. |

I think the OP fetches the properties from an user defined configurable service. For that, you need to use the Broker proxy API. |
