Background documentationMonitoring the Queue Loading and Overflow Locate this document in the navigation structure


You can monitor the queue loading and overflow through the Queue Overflow and Long Running functions within the Threads pane.

This function allows you to view the number of blocked threads waiting to submit a task in the queue of waiting tasks.


You have started SAP NetWeaver Administrator and use the AS Java Overview tool.


Viewing the Queue Overflow
  1. The red traffic light of Queue Overflow indicates that there are no free threads to process.

  2. As a result, the size of the waiting task's queue is full and the threads that need to submit a new task in this queue block wait until a free slot is available.

  3. To resolve the problem with the queue overflow, choose Manage Sessions from the context menu and go to the Session Management application.

Administering Long Running Threads

The Long Running function allows you to view the total number of long running threads on all server processes (nodes) of a certain system.

  1. If there are one or more long running threads, the traffic light is red.

  2. To view the long running threads, choose Manage Sessions from the context menu and go to Session Management.

  3. Determine the session that caused the problem and choose Kill.
