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 SYMPTOMS 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). CAUSE 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. RESOLUTION 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. STATUS Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server.

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.
