Beside a service problem (me personally never tried to insert 50.000 contacts), there is the potential of the .NET lib leaking memory and causing that.
It is most likely not leaking anything at all, but let's try to make sure: a) if it would leak network handles, could you try to batch in let's sizes of 5 and see if you fail earlier? b) if you would leak memory, can you just observer the memory pool to see what happens I believe both are unlikely, but it would be good to verify.
