In LiveUpdate Administrator 184.108.40.206 the Distribution Center Cleanup task will fail when it goes to purge old content from the clu-prod directory. You may also notice that if your LUA is configured to download only Client content, it may also be downloading Manager content as well.
This error is not observed if you choose to download all content for a specific version of the product.
The following error will be present in the LUA event logs:
"Some error occurred while running the purge scheduled for server Default Production Distribution Center."
The following error will be present in the lua-application.log:
"2015-09-25 15:00:01,472 [pool-4-thread-2] ERROR contentrepository.DAOContentRepository - Unknown exception while executing query for getListofCRForDeletedCG
LuaException [UserMessage[ERROR:EXCEPTION_CONTENTREPOS_GET:] Nested Exception is: [ java.lang.IndexOutOfBoundsException ] Index: 0, Size: 0"
and ends with:
"2015-09-25 15:00:01,480 [pool-4-thread-2] ERROR cleanCLU.PurgeCluThread - Exception closing connection for server: Default Production Distribution Center"
This has been resolved in LUA 2.3.5
