Reseed the catalog by using the Update-MailboxDatabaseCopy cmdlet together with the -CatalogOnly parameter. The local database copy experienced an index corruption. Please reseed the catalog by using the Update-MailboxDatabaseCopy cmdlet with the -CatalogOnly parameterJesper Bernle | Microsoft Community Contributor 2011 Awardee

Hi, The database was the active copy. I had failed over the database and performed the above mentioned cmdlet. Once done, i failed over the database back to the original server but the error still persisted. The exact error generated is as follows: EVENT LOG Application EVENT TYPE Warning OPCODE Info SOURCE MSExchange Search Indexer CATEGORY General EVENT ID 122 COMPUTERNAME SINMSX02 DATE / TIME 4/17/2012 10:54:28 AM MESSAGE MS Search (Exchange) reached the memory cap, and now the memory is 7478341632 Bytes. The cap is 4294967296 Bytes

Hi Kevin, Please move some data into this Database. If it is empty or nearly empty may cause this problem. Hope it helps.Rowen TechNet Community Support
