Question

I’m getting an error with the AppFabric Cache Server when I presume a larger object graph gets added to the cache.

ErrorCode :SubStatus:The connection was terminated, possibly due to server or network problems or serialized Object size is greater than MaxBufferSize on server. Result of the request is unknown.

I know for sure its not a network problem. I was able to add a bunch of objects to cache before this particular one. And looking into it, the object is a bit bigger than the others that got added to cache.

How can I adjust the MaxBufferSize on AppFabric Cache?

Answer 1

Client Side it is the maxBufferSize on the transport element in your DataCacheClient config section.

   <transportProperties  ..whatever else you have..  maxBufferSize="8388608"  />

Edit:

Example of the DataCacheClient section from MSDN
