Exchange 2007 - Insufficient system resources

  • 772

I've got an Exchange 2007 server running and have had no issues since it's installation, until now.

There are about 80 Email accounts and the server has a 500GB Hard drive, with about 12GB of free space.

We are now not receiving any emails, they are sitting on our web server in a queue and the Exchange server event viewer is saying Insufficient system resources (Event Viewer error 15006), I've done a search and found this post.

I've not currently got the ability to change the location of the logs, so I thought it might be possible to clear the log instead? - However, I can't find any details on this.

I have however, disabled 'Back Pressure' but we are still not receiving emails.

Does anyone have any suggestions?

    Alleviate your free disk space problem and your email reception problem will go away. Anything else is just going to set you up for an even bigger mess when you completely fill the disks on the server computer.

    Are you doing online backups of Exchange? I have a sneaking suspicion that you're not, and you're building up Information Store database transaction logs. If you don't know where to look, open the "Exchange Management Shell" and (assuming you left your mailbox store in the default "First Storage Group"): get-storagegroup "First Storage Group" | format-table -Property LogFolderPath

    You should only have ".LOG" files in that directory back to your last full online backup. If you're seeing a large number of ".LOG" files in that directory and, particularly if they're old, then you're probably not performing full online backups.

    The "right solution" to that problem is to perform an online full backup. Anything else (switching the database logging mode to circular, performing a rebuild on the information store databases, etc) is a "hack" and isn't solving the problem in the way that Microsoft recommends.

    Edit:

    Your WSUS directory is awfully big, but depending on the products and languages you have selected it's perfectly possible that it would be that big.

    It sounds, to me, like you just need more disk. I'm assuming the rest of your space usage on the disk is in shared folders / files. Is there something there you can remove / relocate temporarily?

    You could move the queue database to another disk. You say you've disabled back pressure, but you're still not receiving email. Double-check your procedure to disable back pressure and see that you really have disabled it and restarted the Transport service.

    Download the above utility on your server and run it, this will help you in getting rid of files in directories you may not know.

    If you are running a backup application to backup Exchange, make sure it is truncating logs (backup app should be exchange aware) - if not, then download a trial of Backup Exec System Recovery 2010 (it is exchange aware, flushes logs, does baremetal restores etc
