PI MDM Issue WARNING: The notification queue contains 9,877 notifications

56 Views

I am having a issue with PI webservices to an MDM Slave repository.

We are receiving a number of warnings about the notification queue, this can cause the Java nodes on PI to go down with out of memory errors.

The scenario's we use are configured with SOAP sender channel sending SOAP requests to PI, We have deployed the MDM services on the PI environment (this is the generated ear file from the MDM repostory) . durring heavy load it seems to trigger this warning [The notification queue contains 9,877 notifications] starting at 1000

Question(s)

1) What's the warning about?

2) How can we reset this counter? (java node restart on the PI invironment works but is not an option to do this every day)

Thanks!!
