getData from a Topic


We have webMethods 9.10 (IS, UM, MWS).
For a client, i have a mistake with Durable subscriber Topic. The Durable Subcriber don’t free the ack.
All messages stays in .mem files (The mem file grow up to10 Go).

The ‘standard’ Topic handles messages well.

I want to use the Java UM API to see the content of the 100 last messaging blocked in the Durable subscriber Topic to ensure that all message are treat and we can delete the mem file.
Can you show me example ?

Can you tell me why the Durable subscriber don’t free the ack when the message is treat ?
