Mailbox grows out of control
Posted on 2006-10-24
Hi. I am fighting a strange problem in my newly installed Exchange 2003. One of the mailbox store grows out of all proportion and I cant seem to find a valid solution as how to stop it or get it under control.
The scenario is as follows: Exchange 2003 Enterprise SP2 / Windows Server 2003 Standard SP1 running on a 2CPU Blade server with 4GB RAM. After installation I migrated mail from Lotus Notes into 4 different mailbox stores in one storage group, approx 200 users 80GB total. I was not able to take a full backup of the Information Store because the stores would dismount, probably because of large amount of logs from the migrate ? The first mailbox store quickly grew from approx. 20Gb to 350Gb in few days without growth in the mailboxes themselves and I thought this was because of it not being able to flush transactions logs due to the backup problems. Anyway, after some consulting I moved all mailboxes from the problem store and removed it and now I am able to take full backups of all stores. However, the same problem is starting with a new mailbox. Yesterday evening I moved a single 500mb mailbox to a new empty storage group and enabled circular logging for testing purposes. As I write this 14 hours later the mailbox is still 500mb but the edb file has grown up to 27Gb and is growing !
One error I am getting is:
MSExchangeIS Event 1160: Database resource failure error Out of memory occurred in function JTAB_BASE::EcRetrieveColumns
Hope anyone has experienced this before
Best regards, Fridrik
