Something like this i have seen on windows 8 with normal usage. not with
opensim.
The p[roblem where finally a wrong used or missing sata / controller
driver for the chipset.

System lockups accompanied with a lot of disk activity are often (but
not always) a sign of insufficient RAM memory. If your system is as
you described and is *functioning properly* then I'd recant my
suggestion that you are low on memory. However, on a multicore system
with lots of extra RAM there isn't really anything OpenSim would do to
cause lockups. Does it happen only when 3D graphics applications are
running? Or, can it lock up when OpenSim is the only program running?

Hi Dahlia,
I don't believe I am low on system memory... It has 11 gigs in it
and only using ~37% of it overall even after running my viewer and
OpenSim for a while and not much else running aside from that
except the occasional browser window and maybe Winamp; although I
do experience the lockups with nothing else running except OpenSim
and a single viewer. OpenSim's memory use has always been ~500 -
600 MB give or take a few of course.
My video card should be more than capable; but I don't usually
have the settings ramped up to the highest for everyday use.
Average CPU use is about ~30% - 40% most of the time; much of it
being my viewer. I have tried setting CPU affinity to processor 3
for the viewer so that OpenSim has the other 3 cores to do stuff
with but to not much avail.
The system was last rebooted about 3 hours ago as of this writing
where I have continued using OpenSim and experienced the lock ups
since then.
Windows was recently reinstalled fresh on the system to rule out
possibility of malware, corruption, or something else screwy going
on there.
I gathered together a few bits of system info that might be
helpful (While OpenSim and a viewer has been running for a while):
OpenSim memory use as reported by show stats command:
MEMORY STATISTICS
Allocated to OpenSim objects: 306 MB
OpenSim last object memory churn : 0.559 MB/s
OpenSim average object memory churn : 1.051 MB/s
Process memory : 599 MB
Memory use as reported by Windows Task Manager:
Total: 11263
Cached: 4553
Available: 7029
Free: 2728
and my system setup:
OpenSim: 10 Region Standalone on 0.7.6 Dev
Physics: Open Dynamics Engine
OS: Windows 7 (x64)
CPU: AMD Phenom II X4 840 3.2 GHz
Video: GeForce GTX 560 Ti (1 GB)
Memory: 11 GB DDR3
Database: MySQL 5.1.63 (x64)
At one point in OpenSim's development not too long ago (I don't
remember exactly when, probably sometime before mid to late
0.7.5's development) this was never an issue; I never saw any
lockups. Nothing has changed on my system hardware wise and very
minimal change has been done on my regions since then except for
the fact that I try to keep my server up to date with the latest
development code when possible. I do understand the risks of this
and I'm perfectly happy to be a tester for it :) I suppose my
question now though is... Why would it be happening in the more
recent code?
I'm by no means an expert when it comes to memory use which is why
I'm asking a ton of questions and trying to provide as much info
as I can think of :) My apologies if I'm asking too many.
Many thanks for the help and suggestions so far!

Sounds to me like you're low on system memory. Try closing some
other applications, especially web browsers with lots of open
tabs. Also try lowering graphics quality and draw distance in
your viewer. If it's Windows and you haven't rebooted for a
while. virtual memory can get rather fragmented and usually use
up a lot of swapping time when Windows decides to move things
around. A reboot can help when this happens.
I'd guess that the timer driven diagnostic might trigger a page
swap to bring in a part of opensim that had been swapped out, and
that might trigger the operating system to move a lot of stuff
around which will lock up the system for a while. You probably
don't see it with the "show stats" command as those pages might
already be resident in memory when you invoke the command.
