We have deployed Mongodb on our production environment with the primary being a Linux CentOS 7.0 and 2 secondary as windows, both running Mongodb 3.4. Its been running for more than 2 years ( We shifted primary to Linux a few months ago) 

Over the last few weeks a lot of errors are started cropping up which read 

An error occurred while deserializing the <Property> property of class<Class>: An error occurred while deserializing the <property1> property of class <Class1>: Attempted to read past the end of the stream.

The <property>, <property1> and <Class1> as well as the last line of the error keeps changing but  Class is usually the same. 

Following are some of the errors of the last line. 

• String is missing terminating null byte.
• Attempted to read past the end of the stream.
• : Detected unknown BSON type "\x45" for fieldname "?". Are you using the latest driver version?
• Expected size to be 838, not 453.

We already updated the Driver version from 2.2.3 to 2.7.0 but the error is still there. 

Can anyone help with this?
