Warp3D leaks memory. At the moment the only workaround is to not regenerate map tiles during the simulator session.
The only fix will be to alter Warp3D itself not to be so braindead (i.e. to properly dispose of the graphics objects
that it creates internally).

I'm encountering a strange issue with one of my regions. It seems that this
one particular region is throwing an out of
memory exception error. This is occurring once every 6 or 7 hours.
Here is a snippet from the log file. It seems to be happening when the sim is
attempting to generate the maptile for
the region. We are currently using the warp 3d maptile module. I've looked at
the region and their really isn't an
excessive amount of content on it; nor are their an excessive amount of scripts
so not sure how to troubleshoot this issue.
Is the out of memory exception error common for the warp 3d maptile module? if
so, is there a fix for it?

Following this line in the log file, there are pages and pages of what appears
to be a binary dump. Is it possible that
the maptile module failed while attempting to generate a texture for this
particular item?
Any direction on this issue would be greatly appreciated.
Kind Regards,
Karl
