Situation Description

Number of buffers on the task's public message queues has reached a warning level.

 

Suggested Actions

Message queue count for the specified task has reached the warning value defined for this situation. The message queue might be backing up due to the following conditions:

  • A program loop (not necessarily on this task)
  • A program hang
  • Unexpected message queue count that exceeds best practices

Issue several TASKMON or TASKUTIL commands to see if the message queue count is dropping. The TASKUTIL command shows the NetView command that is running on the task. If the message queue count remains higher than best practices for an extended period of time, stop the task or notify the system programmer.

Note: Consider putting the TASKMON or TASKUTIL command on a timer to monitor NetView task statistics.
