[Opensim-users] Out of memory exception

[Karl Dreyer]

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
