I'm at something at a loss now - something would have to be generating a very high level of activity to generally
disrupt the running of the system. If you can roughly predict when these happen then perhaps you could watch the
Windows performance monitor and see if it is the OpenSim process that eats the CPU? I should think there are also tools
for recording this data though I haven't investigated such things extensively on Windows.
I presume that you have no alternative machine to try this on?

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.
