[Opensim-users] Region can not start by Yengine error in dev version from yesterday

Thu Dec 13 13:36:48 UTC 2018

YEngine is a new script engine as an alternative to XEngine. It offers 
benefits over XEngine such as micro-threading, better performance, 
faster script compile times, and a stricter script syntax that's 
supposed to be closer along the lines of SL; but right now as far as I 
know it's generally not recommended to use YEngine on a daily basis 
except for testing and bug reporting for it. It's not "secret" so much 
as no one talks about it a whole lot (yet) due to the fact that it's 
still in its experimental stage and it wouldn't be a good idea for 
everyone to go switching over to it and possibly breaking their sims ;)

As far as the crashing issue is concerned though; I am unsure why 
YEngine would be involved in it if you haven't set up your OpenSim 
install to use it. I have pulled the very latest master code today and 
tried it with both XEngine and YEngine with no crashes. It's set up in a 
standard grid mode configuration though (Not HG).
