I'm worried that you may be right about that and it's just a matter of time before adding more content becomes a problem, in which case it sounds like perhaps instead of running all the regions on a single opensim instance I should split them up across several as Gary mentioned above?<div>
<br></div><div>I'm not sure exactly how that works, I guess, and I'm trying to understand how that would use less memory instead of more.. Would I simply copy the contents of the opensim directory to multiple locations and break the regions up in the regions.ini file or..? </div>
<div><br></div><div>I'd like to experiment with it on FleepGrid first before I hose our campus install, but the HGAC group is coming for a visit in a couple days so if anyone has pointers about how to do that splitting up process before I break anything, I'm all ears. :)</div>

I think that it's more likely that the content of the OAR in some way pushed you beyond memory boundaries and wiping it has reset things.<br>

Still, if the problem is solved then that's what matters :)<div><div class="h5"><br>

Hi all,<br>
<br>
After going through the log files and trying to figure out what changed in the time period when the out of memory errors<br>
began, we traced it back to an OAR file import. (Thanks to whoever suggested that might be an issue earlier in this<br>
thread!)<br>
<br>
I'd ported over a copy of the FleepGrid Plaza region so my students could easily grab some of the freebies I'd created,<br>
and it looks like something got horked during the import to the UCSIM grid:<br>

Shortly after that, we begin to see the first out of memory errors..<br>

When we realized it was probably the OAR file that was the source of the issue, I wiped the region by importing a fresh<br>

<br>
Looks like the problem is resolved and super thanks again to everyone who helped with pointers and info in this thread -<br>
much appreciated!<br>

The rrdtools is very good for storing and organizing the data for statistics and it will also produce graphs<br>
from that data. It relies on external scripts to collect the data - that's where Cacti comes in. It has the<br>
scripts and templates to graph your system (and snmp devices) in the distribution. I have done it on Linux and<br>
they claim to work on Windows too.<br>
<br>
You could also write scripts and templates to graph OpenSim. I haven't tried that, though. There is<br>
documentation included in the distro, and scattered across the Cacti user forums.<br>

One question about Cacti, and RDDTools. The sites describe them as<br>
general purpose graphing tools. Is there any documentation or tutorial<br>
for configuring them to monitor system status. Maybe, it's really<br>
simple, and I'm over complicating it.<br>
