Hi all,
I have had this issue for several months now, and has become more frequent over time. Initially it was occuring once a week, if that. Now it seems to occur almost every day.
First, please review this link, describing the exact issue I am experiencing:
http://forums.microsoft.com/technet/ShowPost.aspx?postid=2551837&siteid=17(transcript)
I have an SBS2003 server running Exchange.
Backing up the Exchange server will intermittantly (every 3 to 7 days) hang the server (by hang I mean: no video, no keyboard, no mouse, no network, no disk io, no BSOD).
The event log sequence is:
* ESE 210 start backup
* ESE 220 start priv1.edb
* ESE BACKUP 907 shared memory
*(server stops responding here)
* ESE 221 end priv1.edb (normal execution)
* ESE 220 start priv1.stm
* ESE 221 end priv1.stm
* etc
There are NO event log entries once the server hangs to indicate why the server is hung.

As above, the server completely stops responding after the ESE Backup begins. It does not seem to stop immediately though, as I have had some irrelevant other application entries get logged in eventvwr within 2 or 3 minutes of the ESE Backup event, though within around 10 minutes of the event occuring the server seems to have stopped (Symantec Mail Security looks for updates and logs it every 10 minutes on this server... something else I need to look into but is irrelevent to this scenario).
Sample of events occuring prior to server "hang":
14/12/07 3:46 AM, ESE 220: Information Store (604) First Storage Group: Beginning the backup of the file N:\Exchsrvr\mdbdata\priv1.
edb (size 184 Mb).
14/12/07 3:46 AM, Information Store (604) Backup data transfer method is shared memory (64kb).
(And then nothing else, until customer hard resets server when they come in to work in the morning)
Server hosts Symantec Antivirus 10.1.0.1000 and Mail Security 5.0.2.221. Both of these have had complete uninstalls and reinstalls performed to ensure they are not the culprit.
I also disabled the SBS Backup for 3 days several weeks back to determine if the backup itself was the issue, but the problem seemed to continue (along with the ESE Backup events that seem to be the source of the issue). This I am rather confused about, and am thinking to try this test again to doublecheck this. Thankfully, the site is a relatively small one with very small data change daily.
All basic updates except for Exchange Service Pack 2 have been performed (although this does not seem to alleviate the issue according to the link from Technet).
In most cases, the failures are occuring around 3:40 to 4:00 am in the morning, when the Exchange backup is occuring (the below sample is when the problem DOES NOT occur, there is no log generated and backup does not complete when the problem occurs):
Backup of "SERVERNAME\Microsoft Information Store\First Storage Group"
Backup set #3 on media #1
Backup description: "SBS Backup created on 7/12/2007 at 11:00 PM"
Media name: "Small Business Server Backup (01).bkf created 7/12/2007 at 11:00 PM"
Backup Type: Normal
Backup started on 8/12/2007 at 3:46 AM.
Backup completed on 8/12/2007 at 3:53 AM.
Directories: 4
Files: 5
Bytes: 327,197,234
Time: 6 minutes and 30 seconds
Anyone know this issue and have a solution? Searches online for other people experiencing the same problem have come up with very little, bar the TechNet link I provided above. Unfortunately, there is no solution there, but at least confirmation I am not alone with this problem.
The largest issue in finding information on this problem is the fact there is no error message, no failure event. The only symptom is a complete server freeze requiring a hard reboot and the fact it is almost ALWAYS occuring after the ESE backup of priv1.edb database event called by the SBS backup routine at 4am.
