There was at least 1 known null pointer issue that was resolved by a CM patch. However, to determine if the customer is running into any known issues, it would require deeper investigation and a review of the customer's CM MST logs, which is beyond the scope of assistance provided by this forum. Given the issue is seen at a field site, it is also beyond the scope of DevConnect Technical Support.
Field and operational issues must be escalated by the customer or customer representative through the normal escalation channels to Avaya Client Services or the appropriate business partner holding the maintenance contract on the system(s). This process requires the customer Sold To information and can be initiated through the
http://www.avaya.com/support portal, or via a call to a regional Avaya Support number located on the
http://www.avaya.com/support web page.
Those organizations are equipped with the resources and tools needed to address customer field issues, and have adequate staff to meet the service level agreements of the customer's maintenance contract.
If you are able to reproduce the issue in your own development lab and have a paid DevConnect membership, then please open a DevConnect Technical Support ticket for further investigation.
Best Regards.
