Thanks - trying that now, and I'll report back. If there are any other Mono tweaks that may improve things, I'd be interested; through lack of better knowledge I simply use 1.9.1 out-of-the-box. >What esp does not sound like this bug, is the console freeze.

True, and what I first suspected too, but moving onto another machine entirely didn't make any difference in this case. >-----Ursprüngliche Nachricht----- >Von: [email protected] im Auftrag von John Hopkin >Gesendet: Mo 26.01.2009 01:43 >An: [email protected] >Betreff: [Opensim-users] Odd but persistent symptom [text][bayes] > >Pretty frequently, I've been experiencing lock-ups with OpenSim.exe >that defy all attempts to diagnose by elimination.
