SYMPTOMS
If a Microsoft Operations Manager (MOM) 2005 agent cannot communicate with a MOM 2005 Management Server, the MOM 2005 agent may experience a deadlock situation. This symptom occurs if the MOM 2005 Management Server shuts down or the network communication between the MOM 2005 agent and the MOM 2005 management server is unavailable. The deadlock situation occurs while the MOM 2005 agent is trying to clear the MOM 2005 agent queue after the communication is restored. Additionally, the following events are added to the Application log: Event Type: Error

CAUSE
This problem occurs because of the method that is used to process the backlog. This problem occurs when the scripts are putting lots of data in the queue during the processing. If the queue is full and the communication is restored, the MOM 2005 agent tries to clear the backlog. Therefore, the scripts cannot put the data in the queue when the queue is full.
