[Opensim-users] Intermittent crashing - System.OutofMemoryException

[Fleep Tuque]

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?
