Propagation error when trying to download inventory from server

Question

Hi there,
Has anyone seen the following error when trying to download an inventory from the server.:
Buildfile: C:\bea10.3\user_projects\workspaces\RST\RSTPropagation\21102009\propbuild.xml
import:
BUILD FAILED
C:\bea10.3\user_projects\workspaces\RST\RSTPropagation\21102009\propbuild.xml:39: The propagation servlet returned a failure response: The [Download] operation is halting due to the following failure: null
Additional Information:
The propagation servlet returned the following log information found in [C:\DOCUME~1\myuser\LOCALS~1\Temp\onlineDownload__D21_H11_M8_S11.log]:
INFO (Oct 21, 2009 11:08:11 AM SAST): Verbose logging has been disabled on the server.
INFO (Oct 21, 2009 11:08:11 AM SAST): The propagation servlet is starting the [Download] operation.
INFO (Oct 21, 2009 11:08:11 AM SAST): The modifier [allowMaintenanceModeDisabled] with a value of [true] will be used for this operation.
INFO (Oct 21, 2009 11:08:11 AM SAST): Validating that current user is in the Admin role...SUCCESS
ERROR (Oct 21, 2009 11:08:11 AM SAST): Validating that Maintenance Mode is enabled...FAILURE
ERROR (Oct 21, 2009 11:08:11 AM SAST): Maintenance Mode has not been enabled on the server. With Maintenance Mode disabled it is possible for users to modify the application. This may cause problems for propagation.
WARNING (Oct 21, 2009 11:08:11 AM SAST): Because the modifier [allowMaintenanceModeDisabled] was enabled this validation failure will be ignored and the operation will proceed. However, users will still be able to make modifications to the application, which could lead to missing data and unexpected propagation errors.
WARNING (Oct 21, 2009 11:08:11 AM SAST): The temporary directory on the server used by propagation is [portal/bea10.3/user_projects/domains/RSTDomain/servers/wl_nstf/tmp/_WL_user/RSTEar/7v9j6d/public] with a length of [99] bytes. It is recommended that you shorten this path to avoid path length related failures. See the propagation documentation on how to specify the inventoryWorkingFolder context-param for the propagation servlet.
INFO (Oct 21, 2009 11:08:19 AM SAST): Validating that LDAP and RDBMS security resources are in sync...SUCCESS
INFO (Oct 21, 2009 11:08:19 AM SAST): Writing the inventory file to the servers file system at [{0}].
ERROR (Oct 21, 2009 11:08:23 AM SAST): The [Download] operation is halting due to the following failure: null
Total time: 14 seconds
Please let me know if you have any ideas because "The [Download] operation is halting due to the following failure: null" means nothing to me.
Please note changing the maintenace mode makes no difference.

Please enable Verbose Logging on the propagation servlet

and check the logs on the server, they might give a clue
