ERROR DESCRIPTION:                                              
On Demand Router process becomes unresponsive.                  

LOCAL FIX:                                                      

PROBLEM SUMMARY

USERS AFFECTED:
 All users of WebSphere Virtual Enterprise
(WVE) version 6.1.1.x that have enabled
BBSON - the bulletin board implementation
that uses the unstructured p2p overlay
network (SON).

PROBLEM DESCRIPTION:
A WVE augmented process begins to
consume a large amount of memory and
eventually becomes unresponsive.

RECOMMENDATION:
None

A deadlock condition can occur during a BBSON subject closure
while BBSON is notifying listeners of a new post. The deadlock
causes threads to backup which steadily increases memory
consumption ultimately resulting in the process becoming
unresponsive.

PROBLEM CONCLUSION:                                             
The BBSON synchronization logic has been altered in-order to    
remove the possibility of deadlock during subject closure.      
                                                                
This fix will be included in the next available fix pack for    
WebSphere Virtual Enterprise.

http://www.ibm.com/support/docview.wss?rs=180&uid=swg21205991

The Update Installer for V5.0 does not have a maintenance directory. It uses fixpacks and fixes as the location of the unpacked files.

Customers must be at V6.1.0.17 or newer of the Update Installer.?This can be checked by reviewing the level of the Update Installer in file <was_root>/updateinstaller/version.txt.

1) Copy 6.1.1.0-WS-WXD-IFPM47473.pak file directly to the maintenance directory

2) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that maintenance is being applied to.

3) Launch Update Installer

4) Enter the installation location of the WebSphere product you want to update.

5) Select the "Install maintenance package" operation.

6) Enter the file name of the maintenance package to install (6.1.1.0-WS-WXD-IFPM47473.pak file which was copied in the maintenance directory).  The V5.0 and V5.1 fix packs and fixes are unpacked as .jar files and should be unpacked into fixpacks or fixes directory.

7) Install the maintenance package.

8) Restart WebSphere

Directions to remove fix:  
NOTE:  The user must have Administrative rights in Windows, or be the Actual Root User in a UNIX environments.

NOTE:  FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.
DO NOT REMOVE A FIX UNLESS

YOU MAY REAPPLY ANY REMOVED FIX.

Example:  If your system has fix1, fix2, and fix3 applied in that order and fix2 is to be removed, fix3 must be removed first, fix2 removed, and fix3 re-applied.

1) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that uninstall is being run against.

2) Start Update Installer

3) Enter the installation location of the WebSphere product you want to remove the fix.

4) Select  "Uninstall maintenance package" operation.

5) Enter the file name of the maintenance package to uninstall (6.1.1.0-WS-WXD-IFPM47473.pak).

6) UnInstall maintenance package.

7) Restart WebSphere

Directions to re-apply fix:  
1) Shutdown WebSphere

2) Follow the Fix instructions to apply the fix.
