I have seen the IS service die with a corrupt Exchange database, but I
saw errors in the event log. I defragged the database (which creates a
new database file in the process) and that cleared up the issue for
me...

Subject: Microsoft Exchange Information Store service dies during Legato
Backup
Importance: High

Hi all
 
I have been having intermittent problems backing up our Exchange
servers. Basically, during several failing attempts to backup the
server, the "Microsoft Exchange Information Store" service dies. 
 
*       There is nothing in the event logs to suggest why.
*       It has been happening intermittently on more than on Exchange
server
*       I have been able to restart it on one server at which point the
databases re-mounted.
*       It happened again on the weekend on the second server and I had
to reboot the server as the databases would not re-mount after the
Information store was brought back up.
*       The same symptoms occur on other exchange servers.
 
 
Versions:
Exchange: Version 6.0 (Build 6249.4: Service Pack 3)
W2k: Windows 2000 SP4
Networker: 3.1.0.74
 
 
Legato server: 6.1.3
Solaris Version: SunOS 5.8 Generic_108528-27 sun4u sparc
SUNW,Sun-Fire-480R
                                                                      
 
 
Summary of Details:
*       Exchange server reported down at 5:45am Tuesday morning.
*       I dialed in, found "Microsoft Information Store" service was
stopped and databases unmounted.
*       Noted Legato had attempted to backup the server just before
multiple entries in the event log that suggested the store was down.
*       Log and Application drives all had plenty of space. 
*       No Microsoft entries in the event log to suggest a reason for
the Information store service to have stopped. 
*       I restarted the information store around 5:50am. It took several
minutes to complete starting up and mounting the 4 databases on the
server.
*       I restarted the Networker services at around 6am - thinking that
I should either reboot the entire server or restart Networker services
to ensure the backup worked that night.
*       restarted the failed backup job and it finished without errors
at around 9:45am.
 
 
Has anybody else had problems backing up their exchange servers with the
exchange module?
 
Any help or insights would be great
 
Regards,
 
Andrew
