Ghost images created on package servers go into 'checking package' and/or 'pending download', 'downloading' state after an update configuration occurs on the Symantec Management Agent (SMA) causing significant delays in the processing of other tasks. E.g Copy file, creation of PXE preboots are the main tasks affected as these tasks need to create/copy packages to/from the package server.
There isn't an error per se but all other processes on the package server are delayed until 'checking package' is complete
Ghost images that are created directly on package servers are a special type of package called an 'external package'. In the current design, the hash for these packages is checked every time an 'update configuration' occurs on the Symantec Management Agent whether or not the contents of the package has changed.
Because hashing of one 2gb image file takes approximately 30 seconds and image packages usually contain at least five 2gb files, a significant delay occurs when running the tasks noted in the situation section of this KB. Considering customers have multiple images on a package server the delay can be quite extreme (At least 10 minutes ).
