Event ID 9667 on Exchange Server

[manxra]

Hi,

We have started to get lots of event IDs 9667 on our exchange server (2003).

Failed to create a new named property for database "First Storage Group\Mailbox Store (servername)" because the number of named properties reached the quota limit (16384).

User attempting to create the named property: "SYSTEM"

Named property GUID: 00020386-0000-0000-c000-000000000046

Named property name/id: "different entries"


We got like 8128 events in 5 hours.

Anyone has an idea on this? I found the following link on MS

Thanks
