[Opensim-users] Script engine issue [listeners]

I don't believe that the setting is referencing the number of listeners
in a script.. but rather, the number of listen events per script .. i.e.
the number of times a script can execute the listen capture event ...
based on the scenario it made sense because the scripts would work
perfectly for a random period of time, then a random subset of scripts
would just cease to function. I would imagine that is due to the
fact that those scripts had reached their limit ... so if the
communications between prims such as "server / client" prims
(via llRegionSay) is very active; it could conceivably hit the 64 limit.
I will point out that all of this is hypothesis based on the
behavior I've seen and the reaction to the change I've made in the
opensimdefaults.ini file.
