Windows 8.1 "server" crashing.

Hey all.  I have a system that is crashing every now and then.  It's a Windows 8.1 "server".  Which means it's Dell server hardware with Windows 8.1 on it.

This machine is used as  backup solution using Storage Craft.  The backups are made to this machine, then they are copied offsite.

The issue I'm running into is that the machine crashes and can corrupt the backup job, then we have to start over.

This is all the machine does.  I'm not thrilled with the setup but it is what it is.

I'm attaching a mini dump file.  I tried to look at it, but I'm just not sure how to delve into it and if I did, I'm not sure I'd be able to tell what was going on.

Thans.

Turns out it was a bad stick of memory.  Ran the onboard diags and it showed that stick #2 was faulty.  Pulled it and then re-ran the tests.  They came back fine.

Is there another DMP file to post?  That one shows nothing in Blue Screen View (Nirsoft.net).  I opened it with Ultra Edit but nothing fascinating showed up.

which dell server are you using? Raid controller, does Dell provide drivers for the Hardware?

It seems you know and are trying to contend with the situation as it exists.

Not sure what your setup is,
But their system requirements may explain the situation

Depending on the situation, you might consider using a linux as the backup repository running on the dell hardware...

The error is access violation, the application attempted to access memory resource to which

Arnold...It's a Dell Inc. OptiPlex 9020.

Linux is not an option, nobody here knows much about it.  

It's using the on-board RAID.  No "real" controller.

The backup drives are set up in a RAID1.  However, even that isn't setup as one of the drives failed, and the customer has yet to purchase a second one.

John...that's the only .dmp file I have from that date and time.  There is one from 5 weeks ago, but that was for explorer.exe.  I don't think it's related.

Yeah, that link is kind of telling.  It's a server running Workstation software.  What happened to give you the history was that the owner of the company I work for used to sell backup solutions this way to keep costs down.  Get the hardware and instead of using a proper server OS, he's put on Windows.  

We no longer do it this way, but we have been bitten quite a bit lately.

Can I enable .dmp files to give more information?  If so, please let me know.

Yes, you can enable minidumps.  Here is a how-to for Windows 7, 8 and 10 with the steps listed (better than I could describe in words)

ok,
sata raid on the MB....., check whether the preceding errors dealing with access to the drive.

was the failed drive removed? i.e. it may still be sensed and periodically rears its .......

Yes, advanced settings, but it seems the issue is that the isolation in windows 8 prevents the former blue screen and just dumps the application.

How much memory is in the system?  
Check with the vendor, it seems the OS potentially was switching to something else when the application attempted to access data it had in memory.....

It isn't Server Hardware (shipped originally with Windows 7)

Fixing the Broken Raid 1 would be my first priority

Is the machine bluescreening or just becoming non responsive?

sounds like the application crashes. not the entire system.

not sure the workstaion license from the backup software could manage the data streams that it might be receiving from the clients it is backing up.

check whether the scheduling can be controlled to have the streams at any one time match the software type that is in use.

Found root cause myself.  Other suggestions fine, but didn't point in the correct direction.
