Hi,
I found the reason of the message. My customer uses "F-secure" antivirus software. There are several pages that indicate F-secure causes this message such as [1]. I told my customer to stop F-secure and report to the vendor. Anyway, I think this message is not helpful to administrators and should be lower level such as "DEBUG1".
