Hi Korduri, I expect the threading problem is in your code rather than anything specific todo with the OSG as most of the OSG plugins are thread safe, including the .osg one.
First thing you need to do is review your own threading code - are the shared datastructures mutex locked to prevent multiple threads from writing to the data at the same time? Doesn't look like it to me. Also when taking about crashes with the community provide a stack trace, you really shouldn't be expecting any help if you can't at lest provide this very basic debug trace. Robert.
