HI All,
We are developing a web application for voice base
communication that uses Rhino interpreter at server side (in HttpServlet) to
run the scripts.
If we run this in some limited no of threads (1-5) then it's working fine. But
if we increase the concurrent threads then it throws exception sometimes (4-5%
of calls)
I am using scope object that is shared between multiple threads but a new
context object is created for each thread.
