TITLE   :XADM: Error 4294966767 Appears, Store Stops When Disk Space Low
PRODUCT :Microsoft Exchange
PROD/VER:winnt:5.5
OPER/SYS:
KEYWORDS:

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you run Microsoft Exchange Server 5.5 on a computer that has limited hard
disk space, the Information Store (IS) service may stop unexpectedly, and you
may receive the following error message:

   The Microsoft Exchange Information Store service terminated with
   service-specific error 4294966767.

The following entry may appear in the application log:

   Event ID: 1113
   Source: MSExchangeIS
   Type: Error
   Category: None
   Description: The log disk is full. Attempting to stop the Microsoft Exchange
   Information Store service.

Also, the following entry may appear in the system log:

   Event ID: 7024
   Source: Service Control Manager
   Type: Error
   Description: The Microsoft Exchange Information Store service terminated with
   service-specific error 4294966767.

CAUSE
=====

This behavior can occur when the hard disk drive on which transaction log files
are stored lacks adequate space for creation of another log file. (The Mdbdata
folder in X:\Exchsrvr holds these files.)

RESOLUTION
==========

To resolve this issue, run Microsoft Exchange Performance Optimizer to move the
log files to a different hard disk drive. This drive must have enough space to
hold all the existing logs and still allow the Information Store service to
start up.

To work around this issue if you do not have another suitable hard disk drive,
enable circular logging, or add another hard disk drive and then run Performance
Optimizer.

NOTE: When you enable circular logging, you cannot do incremental or differential
backups. Circular logging automatically writes over transaction log files after
the data they contain is committed to the database.

MORE INFORMATION
================

When the JET database engine detects an 'out of disk space' condition on the
hard disk drive that contains the log file, the following events take place:

 - The JET database engine refuses to take any more transactions from the
   Information Store service or the Directory service.

 - The information store rolls back all uncommitted transactions (this is done
   through use of the reserved log files Res1.log and Res2.log).

 - The information store shuts down, and the JET database engine flushes all
   uncommitted transactions in the log files into the database and leaves the
   databases in a consistent state.
