I keep getting a disk warning 51 message in the system log every few months. It eventually causes the server to crash (killing all my network services), forcing me to do a hard reboot.
Full error (repeats until the server is rebooted):
An error was detected on device \device\harddisk0\dr0 during a paging operation.
I also get (error 6):
An I/O operation initiated by the Registry failed unrecoverably. The Registry could not flush hive: '\??\c:\users\someuser\ntuser.dat'.
I'm running some network/disk intensive applications: one is visual studio 2005 mvc application that collects a data feed, writes some of it to a log file and forwards the whole feed, via a socket, to a java application.
The java 6 application also writes most of the data to a log and some of it to a mysql 5.1 database. I have java 6 update 20 (gonna try updating this).
I know this is a lot of redundant data, but I like to have it around for debugging purposes.
I'm thinking that the network buffers are getting overloaded. This is a Dell Poweredge R710 with a broadcom netxtreme II bcm5709c nic. May try getting another card.
In the past I tried installing the latest windows updates and updating my Dell SAS 6/iR controller driver.
Anyone have an issue like this? Any help is appreciated.

Not to repeat Lamam B but I have done this recently.
Do a backup, ShadowProtect Server is great if you want to mirror the whole thing and drop it onto a new hard disk for minimal down time. I did it a couple of months ago and was back online within 2 hours.
I am sure there is alternatives out there but SP is pretty good.
