<div dir="ltr">System lockups accompanied with a lot of disk

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? <br>

<div>Hi Dahlia,<br>
<br>
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.<br>
<br>
My video card should be more than capable; but I don't
usually have the settings ramped up to the highest for
everyday use. <br>
<br>
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.<br>
<br>
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.<br>
<br>
Windows was recently reinstalled fresh on the system to
rule out possibility of malware, corruption, or
something else screwy going on there.<br>
<br>
I gathered together a few bits of system info that might
be helpful (While OpenSim and a viewer has been running
for a while):<br>
<br>
OpenSim memory use as reported by show stats command:<br>
<br>
MEMORY STATISTICS<br>
Allocated to OpenSim objects: 306 MB<br>
OpenSim last object memory churn : 0.559 MB/s<br>
OpenSim average object memory churn : 1.051 MB/s<br>
Process memory : 599 MB<br>
<br>
Memory use as reported by Windows Task Manager:<br>
Total: 11263<br>
Cached: 4553<br>
Available: 7029<br>
Free: 2728<br>
<br>
and my system setup:<br>
<font color="#000000">
<div class="im">OpenSim: 10 Region Standalone on 0.7.6
Dev<br>
Physics: Open Dynamics Engine<br>
OS: Windows 7 (x64)<br>
CPU: AMD Phenom II X4 840 3.2 GHz<br>
</div>
Video: GeForce GTX 560 Ti (1 GB)
<div class="im"><br>
Memory: 11 GB DDR3<br>
Database: MySQL 5.1.63 (x64)</div>
</font><br>
<br>
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?<br>
<br>
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.<br>
<br>
Many thanks for the help and suggestions so far!

<div>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.<br>
<br>
</div>
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. </div>
