PROBLEM:

One user unable to launch Sametime from desktop shortcut intermittently.

Sametime icon is displayed in tray area however UI is not loaded.

Other application like Excel runs well in Citrix Receiver.

Had to kill Sametime.exe process by task manager.

Environment: Citrix ESXi 6.5, Sametime 9.0 Standalone

Total RAM for Citrix env has 24G, there're 4G free yet.

Diagnostic:

1: Found error in trace-log-*.xml:

java.lang.RuntimeException

at org.eclipse.jface.viewers.ColumnViewer.checkBusy()

at org.eclipse.jface.viewers.ColumnViewer.update()

at com.ibm.collaboration.realtime.imhub.TreeViewerManager.update()

at com.ibm.collaboration.realtime.imhub.ImHubTreeMgr.updateObject()

at com.ibm.collaboration.realtime.imhub.model.Node.doUpdateNode()

at com.ibm.collaboration.realtime.imhub.model.Node.updateNode()

at com.ibm.collaboration.realtime.imhub.model.Node.updateNode()

at

com.ibm.collaboration.realtime.imhub.model.GroupNode.doPropertyChange()

at

com.ibm.collaboration.realtime.imhub.model.GroupNode.propertyChange()

at java.beans.PropertyChangeSupport.firePropertyChange()

 

The org.eclipse.jface.viewers.ColumnViewer.checkBusy() method determines

if it is possible to update the outline. If not it returns an error to

the log.

 

So this suggests Sametime is trying to update the UI while

another update is going on.

2. Logged out and restarted Sametime client after removed workspace files

in %appdata%\IBM\Sametime\ folder.

 

Initially Sametime does not work well, UI responsive slowly though

buddy list loaded successfully and awareness appears to be working..

 

Resolution:

Tuned network parameter following technote #1295167

Domino, Notes client on Citrix and Sametime performance issues traced

to Windows Server 2003 Scalable Networking Pack

 

 

C:\>netsh int tcp show global

Querying active state...

Ok.

C:\>netsh int tcp set global rss=disabled

Ok.

C:\>netsh int tcp set global chimney=disabled

Ok.

C:\>netsh int tcp set global congestionprovider=none

Sametime all features are functioning well after logout Citrix user and re-login.

%appdata%\IBM\Sametime\.config\rcpinstall.properties
