The following error message appears in universe.log every 2 minutes:
o_io_dua_datasender_ensu | Cannot connect to DUA on HOSTNAME:9000


When Dollar Universe Explorer is not reachable or has been uninstalled, every day a file with the name <date>_job is generated in the folder <DUAS>/data/<Area> and will never be purged.

The following variable appears in the values.xml:
U_TARGET_DUA <DUX_server>:<DUX_port> 
(the default port number is 9000)

Cause type: Defect
Root Cause: Dollar Universe Explorer was not removed from the values.xml of the nodes when it was unregistered from the uvms.

OS: All

Workaround:
You should first remove manually all the files YYYYMMDD_job from the subfolders data/XXX of the Dollar Universe nodes.


Solution:
Update to the fix version listed below or a newer version if available.

Fix Status: Released

Fix Version(s):
Component: Application.Server

Additionally, if you still obtain this error in universe.log and the Dollar Universe Explorer is running:
o_io_dua_datasender_ensu | Cannot connect to DUA on HOSTNAME:9000


You need to open the network traffic between your Dollar Universe nodes and the Dollar Universe Explorer server ( listening on port 9000).
