Repeating error in app. log - Can't access SoftwareDistribution.lo

Hello, my Application Log on SBS 2003 Premium R2 is full of following (and
only) errors:

Type: Error
Source: Windows Server Update Services
Category: Service Update Services
Event ID: 503
User: Not available
Computer: EXCHSQL
Description:
The Windows Server Update Services Server experienced an error while
attempting to write to the log file.
9664.20156
System.IO.IOException: The process cannot access the file C:\Program
Files\Update Services\LogFiles\SoftwareDistribution.log because it is being
used by another process.
at System.IO.__Error.WinIOError(Int32 errorCode, String str)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess
access, FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath,
Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess
access, FileShare share)
at Microsoft.UpdateServices.Internal.TraceLogger.Open File()
at Microsoft.UpdateServices.Internal.TraceLogger.Writ eLine(String message)

I have tried many things to solve it as:
Add "WSUS Administrator" rights to the entire folder "C:\Program
Files\Update Services\LogFiles\" and all files in it.
Re-install whole WSUS 2.0 and SBS Update Service.

I got this error almost each time the synchronization runs.
The SoftwareDistribution.log is filling by a lot of messages and looks good.
The Update Service process works well and everything other looks normal and
working.

Can anyone help me how to avoid this annoying error message?

Igor,

It would be best to post this issue to the WSUS newsgroup:
