[Opensim-users] MapItemRequestThread errors

[Sarge Misfit]

Thanks, Justin.

I guess I should clarify, there's 19 regions on my offline standalone, all
nonContiguous. This is the system I use for all my building. Anyway, when I
enter "show thread" I get a Last Update of 1060ms for each region.

I've noticed that the red error messages are showing an increasing period.
When I posted this it was at 5835ms and now they are up to 6584ms.

I'll file a Mantis and will include log entries.
