constant error message

Hi,

I play in OSI shard, and all time razor send me the next message:

System.IO.IOException: The OS handle's position isn't what FileStream expected. Do not use a handle simultaneously in one FileStream and in Win32 code or another FileStream. This may cause data loss.

What can i do? why send this msg?

i am getting a very similar error with only 1-2 lines difference. It pops up suddenly into dozens of windows but does not really affect gameplay (that I can notice).

Any help regarding this would be great.

Also, is there a way to simply stop error message windows from popping up? thanks
