We are running a two node clustered mailbox configuration on Windows 2003 EE x64 SP2, MS Exchange 2007 SP1. We noticed that in the last week, several of our databases are getting corrupted we are having serious downtime on our email. The error which seems to be coming up in the Application Log most often is :
Event Type: Error
Event Source: ESE
Event Category: Database Corruption
Event ID: 467
Time: 10:57:43 AM
MSExchangeIS (3560) Third Storage Group: Database U:\Third Storage Group\Mailbox Database 8.edb: Index Content Indexing Property Store Deleted Items index of table I-3-1 is corrupted (0).

We have 5 Storage Groups with more than 16 databases - total approximate size of Exchange DBs is about 1.4TB (yes it is huuuuge!).
We are repairing these databases with ESEUtil and we are able to recover them but it takes several hours and after that they get corrupted again or other databases get corrupted.
Any advice on where we should be looking to figure out this error message. There are hundreds of these messages in the event viewer.
