Our Exchange 2010 box came up with the following errors this morning, along with some resource exhaustion warning.
' the Exchange store database 'MailboxDatabase' copy on this server appears to have failed due to insufficient memory. The error returned by failover was "There is only one copy of this mailbox database (MailboxDatabase). Automatic recovery is not available.". For more detail about the failure, consult the Event log on the server for other "ExchangeStoreDb" events.
The box only had 5% memory available, we cycled IIS on this box to clear up some memory and the errors cleared. Everything looks to be running cleanly now. no more errors.
My question is, does this mean the DB is corrupted or are we safe to move forward. The box runs all roles of Exchange, and has 8GB of RAM, we were thinking of jumping up to 12GB to see where it lies at that point. Any suggestions would be greatly appreciated.
