We are getting a lot of bundle errors such as:

Error [7/2/10 1:04:39 AM]: pc12345 Bundle

Device IP Address:
Error: [7/2/10 1:04:39 AM] Bundle Bundle.ItemCreationError Bundle.ItemCreationError{e4edfd8fbe073f392248f40cd 492a6ad;The process cannot access the file 'C:\Program Files\Novell\ZENworks\cache\zmd\e4edfd8fbe073f3922 48f40cd492a6ad.APPSTATE' because it is being used by another process.;at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

immediately followed by
Error [7/2/10 1:04:39 AM]: pc12345 BundleManager:

This pair of errors will repeat 3 times with the same date time stamp.

Not all computers are reporting this error. The Bundle causing this error right now is a system bundle Knowledge Base Files (Unmanaged) [3.6.A.12.16]. We have applied TID7006139.

Knowledge Base Files [3.6.A.12.16] is also generating some errors but the unmanged bundle is causing the most errors. What is the difference between the two?
