Exchange Information Store Service Crashing?

Hi,

We are running Microsoft Exchange 2003 on Windows 2003 Server. Our users connect with Outlook Web Access and Microsoft Outlook. We have been having a problem where the email system would suddenly stop working. When people try to connect to Web Access they have been getting a 503.13 error (picture attached). This error is now becomming more frequent. It's allready happened twice this morning.

We have discovered that restarting the Microsoft Exchange Information Store service fixes the problem and allows users to access their email again. In the past it has happened over the weekend and has lasted for hours maybe even a day or two. So I can't see how it can be a "Server Busy" error as the attached picture suggests, because surely once the error occurs, and people stop using the email because they cant access it, it should reset itself?

If it is due to high demand, how many simultaneous connections can it handle? and how can we work around it?
If thats not the problem, then what is? and how do we fix it?

Thanks in advance

Did you check the event logs - application log?
If yes, please post the events specific to Exchange server.

Also check the below link:

Thanks for the reply.

The only thing that looks suspicious in the event log is a warning about MTA connections saying:
"Verify that the Microsoft Exchange MTA service has started. Consecutive ma-open calls are failing with error 3051."

I've attached a picture below. The rest are informational, most of which are related to cleanup tasks etc.
Sorry if the pictures are a bit hard to read, it's because im taking them remotely.

I had a look at the link you posted. The accepted answer contains the following link: http://support.microsoft.com/kb/823440 which suggests a possible solution. However it also states:
"We do not recommend that you use the /3GB switch parameter in the Boot.ini file for Exchange Server computers that are also Active Directory domain controllers or global catalog servers."

Our exchange server is also an Active Directory Domain Controller...

The person asking the question mentions that his/her page file useage slowly increases until the error occurs, then drops again after restarting the information store or server. I haven't been monitoring mine, and im not sure what it is normaly. At the moment its on 3.02GB which to me seems quite high, so maybe the same is happening to me. Next time the error occurs I will check to see if it's any higher.

Thanks

I've just run ExTRA and its given a few problems. One thing that its brought to my attention is our D: drive having less than 10% space left. Some of the other problems are bottlenecks on the drive, which is probably related to the space issue. A replacement drive is being ordered right now. I don't know if that will have anything to do with the problem I was asking about here.

Once the drive has arrived we will need to find a time when we can shut the server down and clone the old drive on to the new one. Once that is done, I will get back to you. Hope this is ok.

Thanks

We've decided to buy a new server which will be a dedicated exchange server and won't be an AD Domain Controller. Our current server runs other software servers aswell as exchange...

Once it is up and running I will use the ExTRA tool to make sure it is running as its supposed to be. If I have any more problems I will open another question.

Thank you for your help,
