Nod 2.7 and Exchange 2007 SP1 application log error

Every 10-15 minutes I receive a Warning:

Event Type: Warning
Event Source: MSExchangeIS
Event Category: Virus Scanning
Event ID: 9874
Date: 16.04.2008
Time: 15:44:45
User: N/A
Computer: ---
Description:
Unexpected error 0x8004010f occurred in "EcProcessVirusScanQueueItem" during virus scanning.
Mailbox Database: /ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=---/cn=Microsoft Private MDB
Folder ID: f-1481D2C
Message ID: 1-2A9CA36B

Everything if fine when i disable XMON.

Error 0x8004010f means "not found". So as far I can tell, something deletes an item before "EcProcessVirusScanQueueItem" tries to scan a message.

The strange thing is that NOD LOGs don't show any caught viruses.

We're running Exchange 2007 Enterprise Edition without Forefront.

 

Did you solve your problem? We have got same problem.

Thanks so much
