[Opensim-dev] Bug or Feature? :( A sim is constantly taking abnormal ram space and eventually crashes after a few hours.

[Teravus Ovares]

I think this may have to do with the asset texture cache.   It might
be worthwhile in the future to reduce it from 24 hours down to
something a bit less permenant.

Best Regards

Teravus

After 15 minutes everything seemed to have settled down and top showed 19.6% of RAM used and 3.7% CPU (P4 2.8Ghz) The console showed 147MB allocated to opensim. Just before I went to bed top was showing 29.2% RAM usage and 1.3% CPU. After 10 hours I looked again, top now showed 24.1% RAM usage and console showed allocated to opensim 204MB. At sometime or other Second Inventory seems to have been used, SI adds its own files sometimes and these are definitely present in the oar.
