Resolve

Free memory from other applications

The MSMQ Service needs adequate memory resources to function properly.

Try identifying and closing other applications that may be consuming a large amount of memory. If it turns out that the MSMQ Service is the only program consuming a large amount of memory, try receiving the messages from the queues or increasing the rate of message processing. For more information, see Resource Management in MSMQ Applications (https://go.microsoft.com/fwlink/?LinkId=107361).

If you continue to get this error, note any details in the event message, and then contact Microsoft Customer Service and Support (CSS). For information about how to contact CSS, see Enterprise Support (https://go.microsoft.com/fwlink/?LinkId=52267).
