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

[Former Member]

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!!

Hi mr P,

We have exact the same issue, please let me know when you found a solution.

Thanks

Having the same errors in log on BPM system. BPM process calls MDM web services. System is up and running without errors, but there are lots of this messages in log.

What is this about? Performance monitor does not show any queues. System restart temporary solves the issue, but this is not the solution.

Hi Alexei,

Did you register a SAP OSS call for this issue?
