[Opensim-users] Intermittent crashing - System.OutofMemoryException

[Gary Banham]

Fleep I'm running into exactly the same problem I check the flotsam cache to
make sure I wasn't using memory 

My server runs windows seven but has the same amount of memory  I have about
8 regions on the server some with quite a few scripts

I rolled back the instance to 7.1.1 to see what would happen and it worked
fine there must be something different in the way 7.2 release uses the
memory

I'm in the process of distributing the regions over a number of 7.2
instances I'm not sure if that's going to cause other problems

Hi all,

 

Our campus opensim system (running version 0.7.2 Release in grid mode) seems
to intermittently be crashing the last week or so and I can't figure out why
or how to reproduce it.  An out of memory exception doesn't make sense to
me, the server has 24GB RAM and has very light load since we're still in
pilot/testing phase.  No more than 5 or 6 users concurrent, only a few sims
with much content..  

 

Does this error mean anything to anyone?
