XADM: Information Store Dismounts and StopsPSS ID Number: 288700

Article Last Modified on 9/10/2001

The information in this article applies to:

Microsoft Exchange 2000 Server


This article was previously published under Q288700
The information store dismounts and starts referencing "version store"
errors similar to the following event: 
Event ID 623

Information Store (2356) The version store for instance 0
("ca192ae5-ad76-478e-8530-0b1756e7d28d") has reached its maximum size of
85Mb. It is likely that a long-running transaction is preventing cleanup of
the version store and causing it to build up in size. Updates will be
rejected until the long-running transaction has been completely committed or
rolled back. 
This is what microsoft says:

Possible long-running transaction: 

SessionId: 0x111006E0 
Session-context: 0x00000000 
Session-context ThreadId: 0x00000B64 

The Application log may also contain a series of MSexchangeIS events (#1022)
and MSexchangeSA events (#9175). 
When the Write Disk Caching (write-back caching on the hard drive) option is
enabled for performance reasons, the Exchange 2000 server may encounter a
JET or information store dismount and crash. 
Restart the computer, and then disable the Write Disk Caching option.
Write-back caching on a disk controller is acceptable so long as the
controller has a battery backup; however, write-back caching on a physical
disk can lead to JET-related issues in Exchange 2000. 
Microsoft has confirmed that this is a problem in Microsoft Exchange 2000

Subject: [exchangelist] Exchange Problem


We had a problem with our Exchange Server 2000 (with SP3) again. Today 
(25/02) about 10:00hs (our local time) all users lost the connection with 
the Exchange Server. All services were running normally and all Mailbox 
Stores were mounted.

During 15 minutes all users couldn't connect to the Exchange Server but 
suddenly the problem disappears and all users could connect to the Exchange 
Server normally.

Searching in Event Viewer we found an event exactly in the moment that the 
problem starts (10:03:14). -> Event ID: 623 - Source: ESE.

Now all users can connect to the server but it is not the first time that 
this problem occurs.

P.S: Our Exchange Server is running in a Windows 2000 Cluster (two nodes).

Can somebody help me?

Thank you.
