Veritas backup causing server to restart and freeze

I am going to provide as much detail as possible.
We have a windows server 2003 r2 with service pack 2 installed. We use Veritas Backup Exec 9.1 Small Business for windows server edition to backup our data every night. Before the beginning of this month, the Backup job was set up to backup all of the exchange data by which we had selected "Microsoft Exchange Mailboxes","Microsoft Exchange Public Folders", and "Microsoft Information Store" from the backup list. We are also backing up various file directories including a very large folder containing about 70 GB of pdf files. The majority of these files were on the local machine that is connected to the backup tape robotic library. The backup takes up on average 140 GB. As of this month we have started using sql server (not sure if that has anything to do with it) and have moved the directory full of pdf files to another server. We have modified the backup jobs accordingly. Now every once in a while, while our backup is running, around 2:00 AM (backup starts at 1:00 AM) the server supposedly (nobody is here) restarts and when it comes back up it is in a non-workable state. The servers raid is solid and the screen is usually at the ctrl-alt-del screen and will not unlock no mater what keys are pressed. usually restarting this server solves the issue but we have had one instance where we had to restart the server 3 times in order for it to get back up and running properly. To me this sounds like some type of exchange problem to me because the only thing in the system logs are messages about the exchange data store online de-fragmentation and deletion of old mailboxes. I don't see any other kind of errors in here.
Can anyone help me?

Are there any errors for Backup Exec in the event logs? What does your job logs say? What errors are listed, if it's restarting then I am guessing it's not finishing the backup?

You are correct about it not finishing the backup. On the job it says that it cant find an xml file so all I see is plain text and there are no errors at all. All I see is:

I am not aware of any other Veritas backup logs. All of the event logs are empty for the time period that it supposedly restarted at.

In the properties of your Daily back up job, do you have it set to eject media after job completes? Or do you have automatic cancelation enabled (if the job takes more than x amount of time)? How do you know the backup is not finishing if you can't read the job History? Does it just say failed? Do you have the Advanced Open file option enabled?

Also are you opening backup exec from the console of the server or  from your workstation?

I'll try to answer all the questions:
No, we do not have it set to automatically eject the media when the job completes. We also do not have automatic cancellation set up. The way I know the job failed is because it says failed on that particular job when looking at the Job History screen. But when I try to open that to see the details it fails with an XML error. The advanced open file option is grayed out and not checked. I am opening the Veritas Backup Exec console from the server itself. And finally, about the XML patch; I will not be able to run that until the weekend because it requires a server reboot. Although I will note that it is not saying that there is an error with a line in the XML file, all it says is: One or more errors were encountered converting the job log into a web page for display. The job log will be displayed in text format. then in the box it has "  C:\Program Files\VERITAS\Backup Exec\NT\Data\BEX02258.xml"
That's all I can see.

That link I sent you will fix that error so we can see the job errors, since there is nothing in the event log whis is going to be tough to diagnose without it.

It doesn't look like my XML parser is at fault here. If I try and open the XML file that it is referring to by explorer, it tells me that it has some un-closed tags. I opened up the file with wordpad and confirmed that there is definitely un-closed tags and it is not a real XML file. The last tag that was closed was "</start_time>" on the Microsoft Exchange Server agent. I know it seems a little impossible to diagnose a problem without any error logs, but is there any way I can turn on some advanced logging just in case this does happen again? It seems to me that whatever is happening is soo bad that it causes the server to do an emergency reboot and doesn't give it any time to log the error.

Also this link may help to set up debugging to find the issue you are having:

We have set up for debugging; however we still have not had this happen again. The service pack may have fixed that.
