Mailbox grows out of control

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

The only reason the stores would dismount is if the drive holding the logs filled up.
This looks like a classic mail loop.

The error message you are getting I am pretty sure is related to a disk space problem. If the stores are growing at such a high rate then disk space is probably an issue.

Have you got message tracking turned on? That may show the loop. Restart the server to break the cycle after enabling it and see what happens afterwards.

Have you run the best practises tool on this machine?



Disk space is not a problem, currently I have some 50Gb free on d:\ where I keep mail and more on e:\ where the logs are. The single user mailbox that I moved to the new empty Storage Group is extremely active, that is, he is getting hundreds of e-mails daily, but its rather the amount of messages rather than the size of them. In fact his current status is some 14.000 messages and 450.000kb. Despite of that the mailbox store in wich he is the only user is now grown to over 30Gb. So what is filling up these 29+ Gb´s ?

Message tracking does not show any loops and running Best Practise Analyzer Tool only suggests that global incoming and outgoing message size is to high but that value has to be higher than reccomended because of certain issues. I dont think that has anything to do with the original problem though.

I am also getting error 9582, Virtual memory is too fragmented and error 1025 "SLINK EcTestMessage", the latter might indicate problems with AntiVirus (Trend ScanMail for Exchange) but I have already had a expert from a Trend partner to check the configuration of ScanMail.

But I do agree that some sort of loop is very likely to be causing this but I dont know where to begin the debug ...

ps. The edb file is up to 31 Gb now .....

I would start looking at the user's mailbox. See if there are any rules in there that could be causing the loop.
I may even be tempted to recreate the user's account, move the SMTP address to a new account and then see if the behaviour continues.



I finally found out what was causing this. The user in question is an advanced technician who adminstrates our company firewall and access lists and he was using an Evolution E-mail client on his Feudora box. I dont know how or why his configuration was having this effect but in addition to using Evolution. he was also using different advanced methods of moving mail between various mail accounts and clients. After learning about it and then convincing him to change his setup, the mailbox store has returned to normal. I still dont understand how any setup can cause this behaviour on the Exchange server though.

Anyway, thanks to Sembee for your efforts.
