Gateway disconnected automaticallly

[Anonymous]

Hi,

I am facing the issue in refreshing the datasets. 
for few datasets the gateway connnection disconnected automatically due to which i am getting an error "Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"  
and again after connecting the gateway the dataset refresh properly (without error). 
I am facing this issue from last 2 days.
Please let me know how can i fix this

how do you know the gateway is disconnecting?  How many cluster members are in your gateway?
