I would actually be rather surprised if errors during the OAR import were related to your memory problems. 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.
Still, if the problem is solved then that's what matters :)

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

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

And we see those out of memory errors stack up until eventually the application
crashed..
When we realized it was probably the OAR file that was the source of the issue,
I wiped the region by importing a fresh
"blank" OAR and we haven't had the out of memory exception since.
Looks like the problem is resolved and super thanks again to everyone who
helped with pointers and info in this thread -
much appreciated!

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

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