Environment

Novell ZENworks Configuration Management 11.2.1 - Agent
Novell ZENworks Configuration Management 11.2.2 - Agent

Situation

WebServerMonitor on managed devices times out and is unresponsive. The agent on the managed device no longer will process bundles, policies, or quicktasks. In the zmd-messages.log there is the following error:

[DEBUG] [10/19/2012 09:21:17.187] [3520] [ZenworksWindowsService] [8] [] [WebServerMonitor] [] [Ping to http://127.0.0.1:7628/RURunning/ timed out after 60 seconds] [] [] 
[DEBUG] [10/19/2012 09:21:17.187] [3520] [ZenworksWindowsService] [8] [] [WebServerMonitor] [] [Restarting the agent web server] [] []

And then there is the same error every hour after that:

[DEBUG] [10/19/2012 10:22:18.109] [3520] [ZenworksWindowsService] [77] [] [WebServerMonitor] [] [Ping to http://127.0.0.1:7628/RURunning/ timed out after 60 seconds] [] [] 
[DEBUG] [10/19/2012 10:22:18.109] [3520] [ZenworksWindowsService] [77] [] [WebServerMonitor] [] [Restarting the agent web server] [] []

Using the command "netstat -na" shows lots of port 7628 connections in a "CLOSE_WAIT" state.

Resolution

Workaround:
Reboot the device.

Cause

The agent web server is stopped and cannot re-start.
