Hi,

Is anyone still seeing this issue occur after applying Vladimir's patch? 
We have applied it to our code, and are still seeing them same 
exceptions arise. It is causing a major problem for us in production 
code, and I'm looking for some feedback from other users out there that 
may be contending with the same thing.

Thanks,
John
