Exceptions in high concurrency.

Hi,

I get a lot of these errors running multi threaded environment :

StructureMap.StructureMapException: StructureMap Exception Code:  400

each thread has its on nested container.

any help would be appreciated

Thanks eyan.

These aren't from the same operation are they?

I'm afraid I don't have an answer for you here.  There might be a problem with something not being locked on the top one, but the real answer is that the nested container mechanics are horrifically bad and copy big data structures around to make each nested container.  This is definitely something I intend to address with 3.0 (actually the main reason that 3.0 is a big release), but it/s not going to happen quickly.

Is there any way you could throttle the number of threads?

Thanks for the reply.

I modified the code, mainly NestedContaners -> new Container + Register, it looks better.
